Copying an Oracle Software "Gold Image" without Cloning?

Hi List
I was hoping to pick the brains of those who've had a similar challenge:
I've automated installation of the Oracle Client in my company via scripted
cloning (unzip the software gold image, run the clone script in the unzipped
home, and finally run root.sh). All the machines needing the client are RHEL
6.x x86-64bit, and a mixture of 11gR1 and 11g2 clients.
This works great for us.
However, our SAs now want to harden the OS build used for App Servers and the
like by excluding tools like gcc. I tried our clone script on the hardened
build and (as expected) the cloned home was non-functional (errors due to
missing libs) and the oracle generated clone actions log reported errors that
gcc could not be found.
The view of the SAs is that we ought to be creating an RPM of the Oracle Client
that doesn't require the clone.pl script, and thus gcc etc. I accept their
point that if all OS build are identical it shouldn't really be necessary to
relink the software and so on.
Initially I wondered if the Instant Client was the answer, but based on my
reading of the docs, it seems to need all the same RPMs as the client.
Removing the RPMs of concern after the client install may be feasible, but we
need to apply PSUs regularly, and perhaps some interims too. I believe opatch
needs these RPMs, so re-installing and then uninstalling the RPMs at patching
time is far from ideal.
All the examples I can find of copying an ORACLE_HOME use clone.pl, including
this blog post which uses a custom RPM:

Assuming my gold image contains (in addition to the ORACLE_HOME) the inventory
directory, oraInst.loc, /usr/local/bin/oraenv etc. AND that the source and
target OS build are identical I can see this *should* work.
Is there anyone out there doing it this way? Does Oracle support doing it this
way, or is clone.pl the only officially mandated approach?
Thoughts from those with some time to spare would be much appreciated...
Thanks
