I didn't cross-check the entire list of dependencies I found with those
reported by rpmbuild, I only checked whether or not the dependencies
that are causing the problem were listed by find-requires or not.  And
as I wrote they are not.

Do I understand correctly that these dependencies are in fact
dependencies for building the CA siteminder agent?  And as such not
needed when running it?
Because as I wrote these dependencies aren't available on the system
where I built the RPM so the binary installer allowed the installation
while it couldn't find those files.

Just to understand these things: then why are both libverify.so and
libverify.so(VER_1) reported as dependency?

In the mean time I remembered that the machine I'm building the RPMs on
is a RHEL4 machine and the machine I'll be installing it on is a RHEL3
machine.  Could that cause problems?  The software itself should run on
both.

Kind regards
