On a related note, env-vars is also being ignored:

env-vars                        =3D =
HOD_PYTHON_HOME=3D/usr/local/packages/python/2.5.1/bin/python2.5

And hod picks the system-default python and terminates with errors =
unless I manually export HOD_PYTHON_HOME.

export HOD_PYTHON_HOME=3D`which python2.5`

I am also having problems having hod use the cluster I created, but I =
assume those issues are also related.=20

How can I make sure that "hodrc" contents are passed correctly into hod?=20=


Thanks a lot in advance!
