I still have to wonder if adding "make install" functionality configurable
with "--prefix=" or the like would be so hard to implement.
It would be nice to tell the build where you want the libs to be put
and have it put them there so you don't have to muck around with
ld.so.conf, or LD_LIBRARY_PATH on Solaris, or whatever else.  Of course,
it's not hard to just move the libs by hand either.  Just a rare nit pick
:)

Well, VTK takes a good three or four hours to build on my dual PII450 with
256MB.  So 11 to 12 hours on the above setup does not seem unreasonable.
If you have plenty of ram you might consider using the "-j" option to
initiate a parallel make.  Obviously with one processor you won't truly
get a parallel build but some of the disk IO can then be done 
asynchronously so you might see a small performance bump from that.
