Perl Compatibility Issues

In general, the 5.6.1 version of Perl is compatible with the previous version, so that scripts do not have to be rebuilt or recompiled to function. However, any XSUB-based (.xs) modules require recompilation and reinstallation.

In the Solaris 9 release, you can access the older version of Perl as /usr/perl5/5.00503/bin/perl. The older version might not be supported in future releases and should only be used until the new modules are rebuilt.
