Hello,
I think I got it installed. I did have have libperl.so but for some
reason it wasn't being picked up by ld.so.conf.
So I:
ldconfig /usr/lib/perl5/5.8.5/i386-linux-thread-multi/CORE/libperl.so
Then I rebuilt the postgresql srpm. And I was able to do:
createlang plperl test
And it worked.
Thanks to everyone that replied.
