Having had a bit of a google, I found this post from Andreas:


So it seems that "python2.4" resolves to one python when cron is running 
and another when run from a shell of the same user.

Has anyone seen this behaviour before or know what could cause it?



PS: I've solved this for now by changing python2.4 to 
/usr/local/bin/python2.4 in the control scripts, which seems to have 
done the trick.
