There has been interest expressed in a way to allow the administrator to
specify default environment 
settings for jobs through the GRAM configuration files.  I'd recommend adding
this to the scheduler-
specific jndi-config.xml files as a simi-colon separated list of name/value
pairs as follows:

<parameter>
  <name>
    extraEnvironment
  </name>
  <value>
    GLOBUS_TCP_PORT_RANGE=1234,4321;GLOBUS_TCP_SOURCE_RANGE=5678,8765;
CONDOR_CONFIG=/fake/path/to/condor_config
  </value>
</parameter>

The GRAM code should user-supplied env vars in the job description over the
values specified in the 
config.
