[postgis-users] PostGIS non functional on Ubuntu 14.04

[Luís de Sousa]

Hi Clifford, thank you for replying. I found an old version of
liblwgeom installed, but after removing it I am still getting the same
error. If you know of other libraries that could be causing this let
me know.

Thank you,

Luís
