You might consider using the *builtin* parser module and forget about
the compiler package if it is broken ( I take your word that it is )
or modern ast representations which aren't really necessary for Python

>>> import parser
>>> tree = parser.suite("def foo():\n print 42}\n")
>>> code = tree.compile()
>>> exec code
>>> foo()

This is also not 100% reliable ( at least not for all statements in
all Python versions ) but it uses the internal parser/compiler and not
a standard library compiler package that might not be that well
