PostGIS 2.0.0 install GEOS issue

Trying to install PostGIS 2.0.0 on Ubuntu 11.10. I've basically followed the OSGeo instructions found here: http://trac.osgeo.org/postgis/wiki/UsersWikiPostGIS20Ubuntu1110src. I built GEOS 3.3.3. If I type `geos-config --version` into the terminal, I am returned `3.3.3`. I can run `./configure` and `make` without issue. `./configure` ends with: ``` PostGIS is now configured for x86_64-unknown-linux-gnu -------------- Compiler Info ------------- C compiler: gcc -g -O2 C++ compiler: g++ -g -O2 -------------- Dependencies -------------- GEOS config: /usr/local/bin/geos-config GEOS version: 3.3.3 GDAL config: /usr/local/bin/gdal-config GDAL version: 1.9.0 PostgreSQL config: /usr/bin/pg_config PostgreSQL version: PostgreSQL 9.1.3 PROJ4 version: 47 Libxml2 config: /usr/bin/xml2-config Libxml2 version: 2.7.8 JSON-C support: no PostGIS debug level: 0 Perl: /usr/bin/perl --------------- Extensions --------------- PostGIS Raster: enabled PostGIS Topology: enabled -------- Documentation Generation -------- xsltproc: /usr/bin/xsltproc xsl style sheets: dblatex: convert: mathml2.dtd: http://www.w3.org/Math/DTD/mathml2/mathml2.dtd ``` All looks good, right? But here's the problem. When I run `make test`, the build fails with this at the end: ``` Creating spatial db postgis_reg createlang: language "plpgsql" is already installed in database "postgis_reg" Preparing spatial db postgis_reg Something went wrong during db initialization (core module). For details, check /tmp/pgis_reg/regress_log make[1]: *** [check] Error 1 make[1]: Leaving directory `/home/anthony/Downloads/postgis-2.0.0/regress' make: *** [check] Error 1 ``` Inside `/tmp/pgis_reg/regress_log` is: ``` SET BEGIN psql:/home/anthony/Downloads/postgis-2.0.0/regress/00-regress-install/share/contrib/postgis/postgis.sql:69: ERROR: could not load library "/home/anthony/Downloads/postgis-2.0.0/regress/00-regress-install/lib/postgis-2.0.so": /home/anthony/Downloads/postgis-2.0.0/regress/00-regress-install/lib/postgis-2.0.so: undefined symbol: GEOSRelatePatternMatch ``` I've tried to ignore the issue and go forward, running `sudo make install` but when I get to setting up my db with `psql -d infinitydb -f postgis.sql` I get a similar problem: ``` SET BEGIN psql:postgis.sql:69: ERROR: could not load library "/usr/lib/postgresql/9.1/lib/postgis-2.0.so": /usr/lib/postgresql/9.1/lib/postgis-2.0.so: undefined symbol: GEOSRelatePatternMatch ``` I've looked around on the net, found one other person with the `GEOSRelatePatternMatch` problem but his was due to multiple GEOS installs. As far as I'm aware, I only have one. Any ideas?
