It did compile and install plper.so in the lib directory.  But when I
try to create a function, it complains that:

ERROR:  Can't find function plperl_call_handler in file
/mypath/perl5/5.6.0/sun4-solaris/CORE/libperl.so

The postmaster restarts itself and does not seem to be leaving
any core file behind for gdb to study.

Using my custom compile of perl:
Here the error that psql gets (includes script):

        This probably means the backend terminated abnormally
        before or while processing the request.

Here is what the postmaster spits out:

How do I get the postmaster to leave behind a core file for gdb to
analyze?  Is the above helpful at all? I do have plperl working on
an earlier version of solaris.

Thanks,
