I was thinking more of two versions of python installed but that doesn't 
look to be the case from what you say. And given mailmanctl imported getopt 
OK how come the execl'd python cannot.

The only difference between execution of the python instance running 
mailmanctl and the execl'd python instance is the -S option on the latter 
while tells python not to automatically run the 'import site' statement 
when it start execution. For instance on my system running python from the 
command line with and without the -S option produces a different value for 
sys.path:

<example>
mailman at mailman2:/mailman/run/bin> python
Python 2.2.2 (#3, Feb 11 2003, 16:57:53)
[GCC 2.95.3 20010315 (SuSE)] on linux2

 >>> import sys
 >>> sys.path
['', '/usr/local/lib/python2.2', '/usr/local/lib/python2.2/plat-linux2', 
'/usr/local/lib/python2.2/lib-tk', '/usr/local/lib/python2.2/lib-dynload', 
'/usr/local/lib/python2.2/site-packages']
 >>>
mailman at mailman2:/mailman/run/bin> python -S

</example>

Try running python from the command line with the -S option and then try to 
import getopt. If this fails then one has to question how python has been 
installed on your system as it would appear that some standard modules are 
installed in the site specific directory rather than their more usual location.
