So, I recently upgraded my Cygwin setup, and broke a Perl script I use
which uses a lot of CPAN modules. Here are the relevant version
details:
setup.exe version 2.682
This is perl, v5.10.1 (*) built for i686-cygwin-thread-multi-64int
/usr/bin/cpan script version 1.9, CPAN.pm version 1.9402
The errors were coming from DateTime::Locale, so I tried reinstalling
it with CPAN, and it failed its tests with errors like these:
Use of uninitialized value $id in pattern match (m//) at
/cygdrive/d/src/.cpan/build/DateTime-Locale-0.44-mPUCHD/blib/lib/DateTime/Locale.pm
line 65.

'replace' parameter as true

line 151.
I saw the same errors going back several versions in the historical
cygwin results at
http://matrix.cpantesters.org/?dist=DateTime-Locale+0.44 , for
example, http://www.cpantesters.org/cpan/report/5378340 -- so they
have been an issue for at least some Cygwin users with different Perl
releases.
I got the module to build, test and install cleanly by running the
dos2unix command on all the *.pm files. So it's a line-ending
thing... I don't know how or why it would be unpacking them with DOS
endings, but I wanted to report the workaround. Maybe it's related to
multibyte .pm files?
I also don't know where the underlying cause or solution would be. Is
there something in Cygwin that should behave differently? Perl?
Cpan? The module itself?
Cheers,
nathan
