That's weird, /usr/lib/perl5/Compress/Raw/Zlib.pm should be loaded
before /usr/lib/perl/5.14.2/Compress/Raw/Zlib.pm.
Reading Ansgar's reply, he seems to have the same idea like me --
some problem with @INC. I just grepped through debmirrors code, but
didn't find INC there.
On my laptop:
% perl -E 'say foreach @INC'
/etc/perl
/usr/local/lib/perl/5.14.2
/usr/local/share/perl/5.14.2
/usr/lib/perl5
/usr/share/perl5
/usr/lib/perl/5.14
/usr/share/perl/5.14
/usr/local/lib/site_perl
.
And in a sid chroot:
# dpkg -l perl libio-compress-perl libcompress-raw-zlib-perl
