[postgis-users] undefined symbol GEOSPreparedCovers on Ubuntu 9.04

[Mike Leahy]

Hello list,

I've just attempted installing PostGIS 1.4.0 on Ubuntu 9.04 (i386).  
Everything seems to work okay up until I try loading PostGIS into a test 
database:

postgres at mgleahy-dev:~$ psql -f /usr/share/postgresql/8.3/contrib/postgis.sql 
test
BEGIN                                                                             
psql:/usr/share/postgresql/8.3/contrib/postgis.sql:53: NOTICE:  type 
"spheroid" is not yet defined
DETAIL:  Creating a shell type definition.                                                        
psql:/usr/share/postgresql/8.3/contrib/postgis.sql:53: ERROR:  could not load 
library "/usr/lib/postgresql/8.3/lib/postgis-1.4.so": 
/usr/lib/postgresql/8.3/lib/postgis-1.4.so: undefined symbol: 
GEOSPreparedCovers

A quick search on the web didn't turn up anything that looked applicable.  Has 
anyone got an idea what might be wrong?

Best regards,
Mike
