[torqueusers] segfaulting pbs_moms: torque-2.3.6-2cri.x86_64

[Tom Pierce]

Dear Douglas,

I had mixed 32 bit moms and 64 bit moms and it did not work well.  I
recovered by switching to a full 32 bit setup for Torque both pbs and
moms.  Later when the full architecture was 64 bit I moved up to 64
bit everywhere.

my two cents.
