I tested using the following test case:
PERL5OPT="-Mstrict -Mwarnings" perldoc -f time
When you first mentioned this in the CB, I had access to perl 5.10.x (RHEL/CentOS/Fedora) and 5.14.x (Cywgin on MSWin), both with as-packaged perl versions. A short time later, I was able to test against a Fedora system with perlbrew, and got the following results:
Perl Version | Errors? (Y/n) |
5.6.2 | Y |
5.8.9 | n |
5.10.1 | n |
5.12.5 | Y |
5.14.4 | Y |
5.16.3 | n |
5.18.4 | n |
5.19.6 | n |
5.20.1 | n |
Hope that helps.
