[OGo-Users] missing libpg.so.4 ... cannot load adaptor bundle PostgreSQL

[users@opengroupware.org]

Following some instructions I found from Adam in the list archives, I 
tried to do an OGO install using the *latest* files from here:

http://download.opengroupware.org/nightly/packages/suse10-2/trunk/

I didn't see any errors during the install using rpm -Uvh *.rpm  (although 
I had to backlevel libobjc from the later one that I'd been using with the 
openSuSE RPMs):

When the installation had finished I couldn't connect through the browser, 
and I found these errors in the log:

dynamic load (dlopen) error:
libpq.so.4: cannot open shared object file: No such file or directory
May 29 14:39:15 ogo-webui-1.1 [7494]: Cannot load adaptor bundle 
'PostgreSQL'
Uncatched Objective-C exception:
exceptionClass <class InvalidAdaptorBundleException>
Reason: Cannot load adaptor bundle 'PostgreSQL'
UserInfo: no userinfo

I checked on my openSuSE 10.3 install that works (the one with the Job 
editing errors), and there is no libpg.so file on there either.

I can telnet to localhost:5432, so PG is running.

The only package that was installed that mentions postgres is this one: 
sope47-gdl1-postgresql-4.7-trunk_r1504.0

I'm stuck. Any suggestions?
