I have fixed up the configure so that if python isn't found the rest of
the configure will still succeed (but python support is disabled). You can
also explicitly force python support to be skipped via the --without-python
configure switch. 

I don't have any platforms without python handy. Could you try the 
latest out of CVS and let me know if it works?

Unfortunately there are a number of dependencies between OGR and GDAL. 
For instance, the gdal/ogr/ogrsf_frmts/sdts depends on gdal/frmts/iso8211
and gdal/frmts/sdts. Regular raster GDAL depends on some coordinate
transform related stuff out of the gdal/ogr directory. 

In theory if you want OGR you should be able to do a configure in 
the gdal directory, then a make in the gdal/port directory, and then a
make in the gdal/ogr directory. In practice you will also need to do
a make in the gdal/frmts/iso8211, and gdal/frmts/sdts directories.

I will think on this.
