Would you please show me a full trace for configuring ("perl Makefile.PL") and building ("make") the module? This looks like a library-finding problem, which usually arises at configure time. -zefram

Seen this before, with the new "multiarch" library layout being sprung on older Perls or old installations. The manual workaround is to hand-edit the "libpth" entries in $archlib/Config.pm and $archlib/Config_heavy.pl to include the correct directories for your system. I'm hoping for ExtUtils::MakeMaker to acquire a workaround, but it doesn't have one yet. -zefram

Thanks for the explanation and workaround. On Tue Apr 24 22:13:37 2012, zefram@fysh.org wrote: Show quoted text

Out of curiosity, is there an RT ticket for this EU::MM work which I can watch?

Thanks; I've added a link between this ticket and that one. In the meantime, the Makefile.PL for XML::Parser seems to provide for this problem by accepting a LIBPATH argument, e.g.: $ perl Makefile.PL EXPATLIBPATH=/usr/lib/x86_64-linux-gnu I don't know if similar functionality could be offered by the Makefile.PL for Time::HiRes, but if so, it would possibly alleviate the need to hand-edit Config.pm and Config_heavy.pl.

Is this anymore relevant / reproducible? If not, I am going to soon close this ticket.
