So I should be OK then with GEOS 2.2.3, it seems.

If I try that on my Ubuntu 6.01 server with GEOS 2.2.1, then it seems to
work OK. I can create a Point() and buffer it and then test if the
buffer contains the point. So it seems to be working there even with the
older GEOS.
However, on my laptop I still get the same error (which is not a
surprise since it was erroring earlier on line 19):
