A rather baffling error message can be "PythonCore not found" when you
start the interpreter and you are sure that PythonCore is available. The
message should actually say "Not enough memory in the system heap to
load PythonCore".
Blame Apple for the confusing message. <p>
Python is a rather safe language, and hence it should be difficult to
crash the interpreter of the system with a Python script. There is an
