up2date aborted with pango.modules conflict

["Chiu, PCM (Peter) " <P C M Chiu rl ac uk>]

We have just acquired a new dual opteron 248 and loaded in RHEL 3
(3.2.3-26).

After setting up the system, I tried to apply the latest updates from RHN,
but it fails with this error:

Test install failed because of package conflicts:
The following packages were added to your selection to satisfy
dependencies:

atk   1.2.4  3.0
glib2 2.2.3  2.0
gtk2  2.2.4  4.0
laus-libs 0.1 56RHEL3
laus-libs 0.1 56RHEL3
mozilla-nspr 1.4.2 3.0.2
mozilla-nss  1.4.2 3.0.2
pango        1.2.5 2.0

file /etc/pango/pango.modules from install of pango-1.2.5-2.0
conflicts with file from package pango-1.2.5-2.0

It is rather odd as the two packages said to be in conflict are identical to
me.

I then tried it again with the -u --force option with up2date,
but it fails with the same error.

I have also tried removing the file pango.modules, no joy.
If I tried to remove the package pango, it complains a huge list of
products requires libpangoft2-1, libpangox etc.
