[tools] mrepo new install question

[Ray Frush]

I just got pointed to mrepo, and so far, I'm really impressed.
However, I'm stuck on the RHN integration.

I installed from the prebuilt RPM:   mrepo-0.8.4-1.el4.rf

According to instructions in:
http://svn.rpmforge.net/svn/trunk/tools/mrepo/docs/redhat-network.txt

I created systemid's for our target distributions thusly:

gensystemid -r 4WS -a i386 /var/mrepo/rhel4ws-i386
gensystemid -r 4WS -a x86_64 /var/mrepo/rhel4ws-x86_64

... and it looks like it worked.   I have new 'hostnames' on the RHN and
a systemid file:
# ls -l /var/mrepo/rhel4ws-x86_64
     total 8
     -rw-r--r--  1 root sys 1326 Jul 12 17:56 systemid


However, when it comes time to get updates with:

# mrepo -uvvvv

I get:

rhel4ws-x86_64: Mirror packages from rhns:///rhel-x86_64-ws-4 to
/mnt/data1/iso/rhel4ws-x86_64/updates
Execute: exec /usr/bin/rhnget  -v -v --delete --username="******"
--password="******" 'rhns:///rhel-x86_64-ws-4'
'/mnt/data1/iso/rhel4ws-x86_64/updates'
Verbosity set to level 2
No RHN systemid found, skipping download.


So, my question is, where is /usr/bin/rhnget looking to find the
systemid file?   What configuration item did I miss?
