Hi!

I had the same promlem, some time ago. It disappeard when i was starting  
the sql-command inside the sourcetree of postgis. Another solution was to  
change the path variable in the sql-statement with the absolute path to  
the lib. No brilliant solution, but it works... ;)
If you have a fresh geos-installation, an ldconfig -v (?) in maybe usefull.
Another thing: you have to ensure, that the postgres-user can read the  
lib, so you have zu check the rw-settings in your /home-dir.

Bye Uwe
