Looks very much like your libgdal.1.1.so doesn't include OGR support. 
Did you do a 'make clean' after you reconfigured your GDAL and before
recompiling and reinstalling it?  Did you also do a 'make clean' in the
MapServer directory before recompiling it?

I guess you could also check that OGR is really included in your
libgdal.1.1.so using the following command, you should see about 30
symbols associated with OGRPolygon:

nm /usr/local/lib/libgdal.1.1.so | grep OGRPolygon

The last thing I can think of would be an issue with the order of the
libraries on the link command, but I don't think I've ever seen this
happening on any platform with MapServer.
