Mike,

Thanks for the reply.

I certainly don't think I compiled anything myself.  I'm on Ubuntu/Debian
and installed postgres, postgis, gdal, and the gdal/ogr Python bindings
with apt-get.  I don't know that I ever explicitly installed proj.4, but I
figured it was installed because I have the cs2cs executable.  I've
installed some other GIS-type stuff like Quantum.

Should I just try:

sudo apt-get install proj

?
