I managed to get a fresh build of IVLE running in Lucid (with a Lucid jail) just by modifying ivle-buildjail to use python2.6 instead of python2.5. So the fix for this should be to make ivle-buildjail somehow smart enough to figure out which version of Python to install.
But I don't think using sys.version is correct -- that will set the jail version to whichever version is running outside the jail, which isn't necessarily correct.
