You have compiled the master branch.

During the current release stage all development work and fixes first go 
in the release-4-5-patches branch, as I wrote. Later those fixes will be 
merged in the master.

Since you have already cloned the repository, you should do:

$ git checkout -t origin/release-4-5-patches

This branch is under heavy development so it may not even compile 
sometimes. Do regular $ git pull to keep updated.

If you run

$ git log -n 1
commit 617c955b9154e2361b3240ede285f3094e5dc621
Author: Rossen Apostolov <rossen at cbr.su.se>

     OpenMM: added support for AmberFF proper/improper torsion potentials.

"commit" is the identifier that would roughly correspond to a "revision" 
in SVN, but the two systems have conceptual differences and the terms 
are not equivalent.

Have a look at some tutorials on the web for a detailed description.

Also, mdrun prints out information about the commit it was compiled from:

$ mdrun
...........

Back Off! I just backed up md.log to ./#md.log.1#
Getting Loaded...
Reading file topol.tpr, VERSION 4.5-beta3-dev-20100812-617c9 (single 
precision)

"617c9" are the first characters of the commit (compare to the git log 
command above)
