I noticed 'glade -v' on this new build on RHEL5 doesn't really work. Normally the UI launches, then I have the lengthy traceback in a window. Now 'glade -v' causes the UI to fail. Here is the stdout/err:
> glade -v
Could not find platform independent libraries
Could not find platform dependent libraries
Consider setting $PYTHONHOME to [:]
'import site' failed; use -v for traceback Glade version
