AFAICT there's only one strict.pm on the box:

# locate strict.pm
/usr/share/perl5/strict.pm
[download]

And there's only one lib.pm in the @INC hierarchy:

# locate /lib.pm
/root/.cpan/build/local-lib-1.008004-GOPHT9/blib/lib/local/lib.pm
/root/.cpan/build/local-lib-1.008004-GOPHT9/lib/local/lib.pm
/usr/lib64/perl5/lib.pm
[download]

The Fedora installation does set PERL5LIB to /root/perl5, but that folder does not exist,

$ echo $PERL5LIB
/root/perl5/lib/perl5/x86_64-linux-thread-multi:/root/perl5/lib/perl5 
# ls -l  /root/perl5
ls: cannot access /root/perl5: No such file or directory
[download]

I'm really stumped.
