Interesting...  this is what I have done:

# rpm -q --scripts lam-libs-7.1.2-11.fc9 > /tmp/lam-libs-scripts
# rpm -e --noscripts lam-libs-7.1.2-11.fc9
# more /tmp/lam-libs-scripts
postinstall scriptlet (using /bin/sh):
alternatives --install /etc/ld.so.conf.d/mpi32.conf \
            mpilibs32 /usr/lib/lam/lam.ld.conf 5
/sbin/ldconfig
preuninstall scriptlet (using /bin/sh):
alternatives --remove mpilibs32 /usr/lib/lam/lam.ld.conf
postuninstall program: /sbin/ldconfig

I have no idea what the tmp file is telling me!  Do you
notice anything of significance?

Thanks!
