That is the idea we have been aiming for.

That would be ideal for the purposes of this project but would affect the 
server which is running a production Apache, GDAL, MapServer, PostGIS 
installation.  We have those system libs for a reason beyond this project.

I would prefer to be running something like user mode linux on this box 
with little to no extraneous libs installed.  That would be the best way 
to create the dumbest base system for testing purposes.  If you do notice 
something odd about the system itself, I can fix it, but we are aiming to 
have everything needed included in the base fgs package.  I can't speak to 
what Frank has done, but thanks for the sleuthing.
