I understand that you are trying to help but I have a few things to
say.  First, this problem is pretty common and a quick search on the
list should tell you that quite a few folks have experienced such
problems.  Some of the users have succeeded in getting it to work.
Secondly, Red Hat is really to blame for shipping with incompatible
software.  I think Red Hat provides a set of updates that fix most of
these problems.  

Kitware does provide rpms and I guess that they are built under Red
Hat 5.2.  Maybe we need to get a more up to date machine building the
nightly RPMS?  We are also trying to get VTK packaged for Debian.
Maitland Bottoms has already uploaded a set of VTK packages into the
unstable tree.  Admittedly these are a bit incomplete but hopefully in
a few weeks we (Maitland and me) will polish things up so VTK works
out of the box under Debian.  If things go well we may see VTK in
woody. :)
