Package: perl-modules
Version: 5.20.2-3+deb8u1
Severity: important
While there were no problems with Debian up to Debian 7,
ExtUtils::MakeMaker now installs perl modules in the wrong
directory. For instance, I build Math-MPFR-3.24 with:
unset PERL_LOCAL_LIB_ROOT PERL_MB_OPT PERL_MM_OPT
mkdir $HOME/testdir
perl Makefile.PL PREFIX="$HOME/testdir"
make
Then:
$ make install
[...]
Appending installation info to
/home/vlefevre/testdir/lib/x86_64-linux-gnu/perl/5.20.2/perllocal.pod
Files found in blib/arch: installing files in blib/lib into architecture

This is wrong because perl won't search the modules in
"$PREFIX/lib/x86_64-linux-gnu/perl/5.20.2".
$ PERL5LIB=$HOME/testdir/lib/perl perl -MMath::MPFR -e ''
Can't locate Math/MPFR.pm in @INC (you may need to install the Math::MPFR
module) (@INC contains: /home/vlefevre/testdir/lib/perl /etc/perl
/usr/local/lib/x86_64-linux-gnu/perl/5.20.2 /usr/local/share/perl/5.20.2
/usr/lib/x86_64-linux-gnu/perl5/5.20 /usr/share/perl5

The perlrun(1) man page says:
PERL5LIB A list of directories in which to look for Perl
library files before looking in the standard library
and the current directory. Any architecture-specific
and version-specific directories, such as
version/archname/, version/, or archname/ under the
specified locations are automatically included if they
exist, with this lookup done at interpreter startup
time. [...]
To follow the PERL5LIB convention, the files should not have been
installed in
$PREFIX/lib/x86_64-linux-gnu/perl/5.20.2
but in
$PREFIX/lib/perl/5.20.2/x86_64-linux-gnu-thread-multi
for which I do not get an error.
