That doesn't seem right, there's no length() or scalar assignment in line 4000 of Module/Build/Base.pm version 0.2808. That line is: return $self->do_system($perl, @$args); Is that the same line you see? Are you able to poke around and see what's going on? -Ken

nadim@localhost ~ $ pmvers Module::Build::Base /usr/bin/pmvers: unknown version for module `Module::Build::Base' nadim@localhost ~ $ pmvers Module::Build 0.2806 see snapshot for the line. I will update to the latest version and test.

just updated to the latest version. I get something else now. nadim@localhost /devel/perl_modules/List/Tuples $ perl Build.PL Deleting _build Creating custom builder _build/lib/List/Tuples.pm in _build/lib/List Can't call method "version" on an undefined value at /usr/lib64/perl5/vendor_perl/5.8.8/Module/Build/Base.pm line 982. that would be here: sub find_module_by_name { # Method provided for backwards compatability return Module::Build::ModuleInfo->find_module_by_name(@_[1,2]); } I subclass M::B if that is of interest. I have created a new module for test: nadim@localhost /devel/perl_modules/x/y $ perl Build.PL Creating custom builder _build/lib/x/y.pm in _build/lib/x Checking whether your kit is complete... Looks good Checking prerequisites... Looks good Creating new 'Build' script for 'x-y' version '0.01' the interesting part is that 'perl Build.PL' works for thex:y module but not for module List::Tuples. I did a './Build dist' for module x:y and I still get 'Use of uninitialized value in length at /usr/lib64/perl5/vendor_perl/5.8.8/Module/Build/Base.pm line 4000'.

The error message is right. I was just a bit too zealous and removed the lib directory while doing tests :)
