Robin,
since Boa, PythonCard, wxGlade (what else?) make fairly heavy use of
wxPython features it might make sense before you do a all the builds to
simply try and run each of the base tools using the latest versions in cvs
with the Windows or Linux build of wxPython you're working on. Since we're
all keeping as up-to-date as possible, if those tools won't startup or
exhibit and obvious problem after startup then maybe the issue can be
tracked down and fixed before you go to the trouble of making all the
different builds on each platform? Chandler is another obvious test, though
I don't know how much that already deviates from what the rest of us are
using.
In the case of PythonCard, running with the Debug menu
python PythonCardPrototype\samples\minimal\minimal.py -d
will do the basic test including loading the shell.
samples\widgets\widgets.py
tests a little wxDC and wxHTML and might be quicker than running through
every control in the demo for a quick check.
Just trying to start Boa always seems to test a lot of wxPython
