The bugs database, http://bugs.perl.org
doesn't have any open bugs mentioning NetWare.
Note that man perlport points you to the
ports directory on CPAN for the NetWare
ports. Also from man perlport:
A free perl5-based PERL.NLM for Novell Netware is
available in precompiled binary and source code form
from http://www.novell.com/ as well as from CPAN.
The manual page does list 5.003_07
release that's ported to NetWare though (but that information
could be outdated). The reason such an old version of Perl
is the only one available is that noone was interested enough
to do the port.
