So which python is first in your PATH?

$ which python

Hi Paul,

[alastair@d6173 alastair]# which python
/usr/bin/python
[alastair@d6173 alastair]#

The App I believe to be the culprit was installed with a shell script.  I didnt look at it closely and now its disappeared!

Any ideas on how I can bring python back to life?

Best regards and thanks,

Alastair
