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The manual page does list 5.003_07 as the release that's ported to NetWare though (but that information could be outdated).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.
