Yes. That is why my first thought was there were 2 different Python 
installations on the machine with the first being picked up through your 
$PATH and the other through mm_cfg.PYTHON. But you say this is not the case.

My second thought was hasty and wrong.

With execl the executed program should find itself with the same 
environment as the program that launched it and running with the same 
process ID which is why this is so odd. Now if it were execle then a change 
in environment would be explicable but that isn't it.

Back to which OS and which Python version.
