We get around this problem by having users explicitly launch bash in login
mode in their submission scripts.

#!/bin/bash -l
#PBS -l <resources>

This actually works just fine.  The module command itself is really just a
shell function:

% grep 'module()' /usr/local/share/modules/init/bash
module() { eval `/usr/local/modules/$MODULE_VERSION/bin/modulecmd bash $*`; }

The module init script needs to be sourced, and the only way I've been able
to get this to work reliably is to use bash in login mode.  If you're using
tcsh, it should act like a login shell by default, in which case I have no
idea what's causing the problem you're seeing.
