PlPERL and shared libraries on Suse

Hi,
I have an installation of Postgres 7.4.2 on SuSE 9.1. This version
of SuSE comes with a binary for plperl and several other postgres
procedural languages. All the others, including plpgsql install without
a problem, but executing:
createlang -u postgres plperl template1
produces the result:
createlang: language installation failed: ERROR: could not load library
"/usr/lib/postgresql/plperl.so": libperl.so: cannot open shared object
file: No such file or directory

The file, however, is there:

# ls -l /usr/lib/postgresql/plperl.so
-rwxr-xr-x 1 root root 37097 Apr 5 2004 /usr/lib/postgresql/plperl.so

Some googling gave me the idea that it may be a problem with the way
perl was compiled - i.e, perl is not compiled for shared libraries. Can
anyone confirm this? If so, do I need to rebuild perl, or pl/perl, or
both? Are there any binaries that can resolve this? (yes not wanting
to compile plperl is plain old laziness, but I do have reservations
about recompiling the perl interpreter)

Any ideas would be helpful.

Thanks,

Eric
