Re: perl5162-core build/install problem on case-sensitiveFS

Hi Dan,

thanks for the pointer, this seems to be a bigger can of worms than I've thought!

Perl has fought with this issue for years, and even this specific instance of it. Apparently the .pod is the remnant documentation regarding the actual perl-module fix (maybe there had been a version/Internals.pm that was renamed). See:

Indeed, so renaming the directories in the source tree does not help, as perl immediately
complains at the beginning of the build. So I tried the less nice approach of fixing things up
afterwards, hoping, as the list mail above indicated, that this would not mess up namespace things, 
but I am certainly a bit over my head into this… With the following changes

perl5162-core and perl5162 build and install in maintainer mode (though the latter has a name conflict
with json-pp-pm - is that package unversioned on purpose?).

But building any of the modules (e.g. test-harness-pm5162) fails at the step

ARCHFLAGS="" /usr/bin/arch -x86_64 perl5.16 Makefile.PL PERL="/usr/bin/arch -x86_64 perl5.16" PREFIX=/sw INSTALLPRIVLIB=/sw/lib/perl5/5.16.2 INSTALLARCHLIB=/sw/lib/perl5/5.16.2/darwin-thread-multi-2level INSTALLSITELIB=/sw/lib/perl5/5.16.2 INSTALLSITEARCH=/sw/lib/perl5/5.16.2/darwin-thread-multi-2level INSTALLMAN1DIR=/sw/share/man/man1 INSTALLMAN3DIR=/sw/share/man/man3 INSTALLSITEMAN1DIR=/sw/share/man/man1 INSTALLSITEMAN3DIR=/sw/share/man/man3 INSTALLBIN=/sw/bin INSTALLSITEBIN=/sw/bin INSTALLSCRIPT=/sw/bin
arch: Can't find perl5.16 in PATH

(there is /sw/bin/perl5.16.2 in PATH, and the equivalent works for "arch -x86_64 perl5.12" vs. /sw/bin/perl5.12.3; 
"/usr/bin/arch -x86_64 perl5.16.2" apparently works as well, but here not without the full versioned name).
I don't know if this is somehow due to Internals.pod now possibly not being found - it seems to contain some
versioning information, but I really don't know anything about perl internals at this level…
