As for tcl/tk 8.4, the plan is that we build python against the same version used by the ftools (sometimes referred to as heasoft). We have a copy of heasoft installed at SLAC, currently on a rh9 build..but I'll be doing a rhel4 build soon. That build is located at $GLASTROOT/applications/heasoft/
We should confirm have confirmed with Jim Chiang whether that it is numpy or (rather than numarray) we should be supporting. I no longer recall which is the more recent module...and I vaguely recall some of Zach Fewtrell's code used the older of the two - perhaps that has changed since last year.
