A common variant on an unreadable file is that the directory which the file may or may not be in is itself unreadable (perl doesn't distinguish between these cases). So the OP likely has PERLLIB or PERL5LIB including an unreadable directory.

The almost-released perl-5.22.0 improves the error message by indicating which path failed: 

$ export PERLLIB=/root

$ perl-5.16.0 -Mstrict -e1

$ perl-5.18.0 -Mstrict -e1
Can't locate strict.pm:   Permission denied.

$ perl-5.20.0 -Mstrict -e1
Can't locate strict.pm:   Permission denied.

$ perl5.22.0-RC2 -Mstrict -e1
Can't locate strict.pm:   /root/strict.pm: Permission denied.
