Bug #72948 for XML-Parser: library and headers differ

It sounds like the issue is related to how linking happened on OSX. 1. which perl are you using? 2. Which libexpat are you expecting to use? 3. When you built XML::Parser, was LD_LIBRARY_PATH set? 4. output from perl -V would help I notice you mentioned 2 installs. Let's simplify the issue at the moment. Just pick one and send me that information?

First a couple quick questions and then below are the answers to your questions:  If I do some editing of the makefile by hand, is that a possible solution?  What are typical values for LD_LIBRARY_PATH and for the location of libexpat?  Would it help if I sent you Makefile and Makefile.PL ?  thanks for your help Answers to your questions: 1) perl -v gives following: This is perl, v5.10.0 built for darwin-thread-multi-2level (with 2 registered patches, see perl -V for more detail) 2) I don't know how to answer this question, sorry.  If you can tell me where to look on my system to answer this, I will be glad to look.  I'm reasonably competent with UNIX but don't know much about perl. 3) Same answer as 2, however I think the answer might be "no" - I didn't edit the make file or anything like that to set LD_LIBRARY_PATH.  If there is a default value then that is probably what was used. 4)  output from perl -V is below Summary of my perl5 (revision 5 version 10 subversion 0) configuration:   Platform:     osname=darwin, osvers=10.0, archname=darwin-thread-multi-2level     uname='darwin neige.apple.com 10.0 darwin kernel version 10.0.0d8: tue may 5 19:29:59 pdt 2009; root:xnu-1437.2~2release_i386 i386 '     config_args='-ds -e -Dprefix=/usr -Dccflags=-g  -pipe  -Dldflags= -Dman3ext=3pm -Duseithreads -Duseshrplib -Dinc_version_list=none -Dcc=gcc-4.2'     hint=recommended, useposix=true, d_sigaction=define     useithreads=define, usemultiplicity=define     useperlio=define, d_sfio=undef, uselargefiles=define, usesocks=undef     use64bitint=define, use64bitall=define, uselongdouble=undef     usemymalloc=n, bincompat5005=undef   Compiler:     cc='gcc-4.2', ccflags ='-arch x86_64 -arch i386 -arch ppc -g -pipe -fno-common -DPERL_DARWIN -fno-strict-aliasing -I/usr/local/include',     optimize='-Os',     cppflags='-g -pipe -fno-common -DPERL_DARWIN -fno-strict-aliasing -I/usr/local/include'     ccversion='', gccversion='4.2.1 (Apple Inc. build 5646)', gccosandvers=''     intsize=4, longsize=4, ptrsize=4, doublesize=8, byteorder=1234     d_longlong=define, longlongsize=8, d_longdbl=define, longdblsize=16     ivtype='long', ivsize=4, nvtype='double', nvsize=8, Off_t='off_t', lseeksize=8     alignbytes=8, prototype=define   Linker and Libraries:     ld='gcc-4.2 -mmacosx-version-min=10.6', ldflags ='-arch x86_64 -arch i386 -arch ppc -L/usr/local/lib'     libpth=/usr/local/lib /usr/lib     libs=-ldbm -ldl -lm -lutil -lc     perllibs=-ldl -lm -lutil -lc     libc=/usr/lib/libc.dylib, so=dylib, useshrplib=true, libperl=libperl.dylib     gnulibc_version=''   Dynamic Linking:     dlsrc=dl_dlopen.xs, dlext=bundle, d_dlsymun=undef, ccdlflags=' '     cccdlflags=' ', lddlflags='-arch x86_64 -arch i386 -arch ppc -bundle -undefined dynamic_lookup -L/usr/local/lib' Characteristics of this binary (from libperl):   Compile-time options: MULTIPLICITY PERL_DONT_CREATE_GVSV                         PERL_IMPLICIT_CONTEXT PERL_MALLOC_WRAP USE_ITHREADS                         USE_LARGE_FILES USE_PERLIO USE_REENTRANT_API   Locally applied patches:     /Library/Perl/Updates/<version> comes before system perl directories     installprivlib and installarchlib points to the Updates directory   Built under darwin   Compiled at Jun 24 2009 00:35:28   %ENV:     PERL5LIB="/sw/lib/perl5:/sw/lib/perl5/darwin"   @INC:     /sw/lib/perl5     /sw/lib/perl5/darwin     /Library/Perl/Updates/5.10.0/darwin-thread-multi-2level     /Library/Perl/Updates/5.10.0     /System/Library/Perl/5.10.0/darwin-thread-multi-2level     /System/Library/Perl/5.10.0     /Library/Perl/5.10.0/darwin-thread-multi-2level     /Library/Perl/5.10.0     /Network/Library/Perl/5.10.0/darwin-thread-multi-2level     /Network/Library/Perl/5.10.0     /Network/Library/Perl     /System/Library/Perl/Extras/5.10.0/darwin-thread-multi-2level     /System/Library/Perl/Extras/5.10.0 Show quoted text
