Hi JP,

> That didn't seem to resolve the problem, but i am not sure I installed everything properly. I am a little out of my depth as far as the ins-and-outs of Macports packages go. Maybe someone else can give it a try and see if it works for them (if they have the problem - since no one else seemed to have this problem here, maybe there is just something messed up with my configuration).

Sorry it did not work. It is definitely not a problem with your configuration. With the current GNUMakefile in the swig/python directory of gdal, the python plugins go in /opt/local/lib/python26/… instead of /opt/local/Library/… so that is definitely a bug.

Strange, as I can see no '.' at the end of my patch file. Anyhow, I'll file a bug report/enhancement request asking to bump to 1.7.2 and solving this bug.

My own version works, as far as libspatialite is buggy:

I hope we will integrate the patches quickly into the mainstream so that you can recompile it without to worry about overriding files here and there.

Have a nice week-end meanwhile
