Drew, Rob, Frank, ...

I guess the error message should be more explicit, but what it means is
that configure looked for all the following files:
 ogr_feature.h, ogrsf_fmrts.h, cpl_conv.h, ogr.a, ogrsf_frmts.a, cpl.a
and at least one of them could not be found.

It is likely that you had not yet compiled the OGR tree at the time you
ran configure and one of the .a files was not found.  Was it the case?

As Rob noted, there are several ways to compile GDAL/OGR independently
or not in MapServer and perhaps that's not well enough documented (if at
all!?!):

1- OGR only statically linked into MapServer, then you point configure
   directly to the ogr source tree after having compiled OGR:
     configure --with-ogr=/path/to/ogr/source

2- GDAL only using libgdal.so installed in system lib dirs, this assumes
   you have previously run 'make install' as root in your GDAL source
   tree:
     configure --with-gdal
   or 
     configure --with-gdal=/usr/local/bin/gdal-config
   (or whatever the path to the installed gdal-config script is.)

3- GDAL and OGR using libgdal.so.  Same as #2 above, but add --with-ogr
   with no argument:
     configure --with-gdal --with-ogr
   or 
     configure --with-gdal=/usr/local/bin/gdal-config --with-ogr

I'll copy these notes in the README.CONFIGURE

I hope that helps.
