clue on sparky

[Jack Howarth <howarth@bromo.msbb.uc.edu>]

    I believe I may have a clue as to why sparky is segfaulting in
when run as a python extension. The upstream maintainer is using
python 2.1.1 and tcl 8.3.4 so I built against our python 2.1.3 and
tck 8.3.3. However I just noticed that sid's python2.1 is in
fact built against tcl-8.4 now. Could this case problems if one
builds a python2.1 module against tcl8.3 instead and try to import it?
I tried building sparky against tcl8.4 but got errors of the form...

g++-2.95 -O2 -fPIC -I/usr/include/tcl8.4 -c /usr/local/src/sparky/c++/winsystem-unix.cc
In file included from /usr/local/src/sparky/c++/winsystem-unix.cc:9:

..etc. Anyone have any idea how to properly handle those?
