It makes a big difference if you skip the extra kits and if you don't
do the tcl, python wrapping.
Prabhu: even on a single-cpu machine, 'make -j 2' speeds things up a
fair bit. A lot of RAM helps too. Typically it takes me about 15-20 min
to build all of VTK + wrapping (with -02 optization) on the 2x933 PIII
1GB RAM in our lab, using gcc-2.95.3. The build is done off of a network
disk, which might slow things down a bit.
