general trouble installing languages

I suspect at this point I may need to recompile things?  I'm not sure
what the trouble is.  Can I try the directions in
http://www.postgresql.org/idocs/index.php?plperl-install.html
in lieu of a complete recompilation?  The runit does indicate that
with-perl was included, so I don't understand why this didn't
work, but perhaps (see below) because the timestamps are different?

I didn't have any better luck with trying to createlang on plpgsql either...

......

(Also, trying to link libperl.so.1 to libperl.so failed.  And I don't think
it's a shared library problem, as I'm not getting that message anywhere.)

The error message is now a bit more detailed:

> createlang -L /usr/local/pgsql/lib -d Text plperl
ERROR:  Load of file /usr/local/pgsql/lib/plperl.so failed: ld.so.1: /usr/local
/pgsql/bin/postmaster: fatal: libperl.so.1: open failed: No such file or direct
ory
createlang: language installation failed

I am running this command from the account under which psql was installed
& started (which shd be superuser).

I do note that:

is earlier than the dates of the compilation in the src/pl dir:

Hm....???  Perhaps recompilation is in order...  Or just reinstallation?
(of what?  no .so file here)

Thanks,
