Yes, this is almost definitely a Python issue.  A common cause for this is that 
Python has been (rather quietly) disabled because Twisted wasn't installed.  In 
destiny, this is now an error rather than a warning.  So the first thing you 
might want to do is check that you have Twisted installed and/or check the 
output of ./configure to see if it mentions disabling Python.

Failing that, can you send your config log?
