Hi,
thanks to these comments, I worked out where to start looking to fix my issue.

I had postgres installed via EnterpriseDB which bundled an old version of postgis.
I installed the following libraries from source:
geos
proj4
postgis

but postgis failed to install with a similar error: undefined symbol: GEOSHausdorffDistance

after moving old lib files and replacing with new copies from /usr/local/lib it worked for me:

1) backup lib files:
cd /opt/PostgresPlus/8.4SS/lib
mkdir backup
mv libgeos* backup
mv libproj* backup

2) copy in newer lib files
cp /usr/local/lib/libgeos* ./
cp /usr/local/lib/libproj* ./

after thses steps, running the postgis.sql script worked.

Ouch, it took me about 15 minutes to find your post, plus another hour since I first tried fixing this myself. Didn’t expect a THAT easy solution, but thanks alot!

I was getting the same error. “ldconfig” did not help, but I used “ldd” and found some old LibXML libraries. I then searched for old GEOS library files and found some in the PostgreSQL utils library.

I removed the libgeos files from the PostgreSQL utils library, and the PostGIS installation worked.
