Following Traudl's lead, I downloaded the Gaudi v7 release, and extracted the following packages:

ExternalLibs v3 
ROOT v2r25p1 
CLHEP v1r6 
HTL v13p1 
GaudiPolicy v4r3
GaudiKernel v9 
GaudiDb v3 
RootHistCnv v3 
GaudiTools v3 
GaudiAlg v3 
GaudiAud v3 
GaudiSvc v5
GaudiExamples v7

I made modifications to:

ExternalLibs

Had to set LHCXX_DIR and \extlib and ROOT_DIR to \extlib\ROOT on my system. This was sufficient for HTL 1.3.0.1 that we are using now, CLHEP 1.6.0.0.

ROOT

Changed path from v2.25/nt4/root to 2.25.03. If this is a new convention, we should consider changing. (Moving to ROOT 3.0 is another issue.)

GaudiSys

This is a "checkout" package, with only use statements for the system, no constituents. It also has complete doxygen output for the system, under doc/html. [vcmt now assumes this path, so you can just click the examine button.]
I commented out use statements for packages not in this initial test, and hbook-related stuff.

GaudiExamples

Commented out a few packages not in the list for now, and switched HBOOK to ROOT in the requirements file and the job options.

That is it! No code changes. The result all builds on NT with vcmt v8. A zip file, gaudi_v7.zip, is accessible here.

Build/test instructions (NT/vcmt)

Make sure you have the latest CMT v1r7. (We are waiting for it to become v1r8 before putting it into our repository, but here is a zipped copy of my download/build)
Download the above zip file, unpack it with folder paths: it will all go into gaudi_v7.
Make sure the latest vcmt v8 is installed, and start it. (Or use vcmt to download it.) [Note: this is backward compatible, it can be used with the old code. CMT v1r7 is not backward compatible; keep v1r5p1 around!]
Setup CMT version to be v1r7 (build if necessary), and set the CMT paths to only the above folder. If you set site to GLAST_NT, then you will get the mods I made to ExternalLibs, assuming /extlib has all the exernal libraries.
Select the GaudiExamples package, set broadcast, and click setup.
Select the project RandomNumber-app, and click make.
In the app parameters window, type "home/RandomNumber.txt" and click run.
You should see that three histograms were created, and find the converted root output in the file histo.root.

Final note: this is a much better designed system. I am looking forward to installing it and taking advantage of the better architecture and and cleaner build system.
