I was sure I had run scripts/updateSCCSVersions before, but running it
again fixed the problem
  $ cd ~/Repos/OpenSmalltalk/vm
  $ rm -r *
  $ git checkout -b firstbuild Cog
  $ git reset --hard HEAD   # not sure if this is the best command to use
here
  $ scripts/updateSCCSVersions
  $ cd build.linux32x86/squeak.cog.spur/build
  $ ./mvm
clean? y
Libraries have been installed in:

 /home/ben/Repos/OpenSmalltalk/vm/products/cogspurlinuxht/lib/squeak/5.0-201606230315-firstbuild

However...
  $ git checkout -b secondbuild Cog
  $ /mvm
clean? y
Libraries have been installed in:

 /home/ben/Repos/OpenSmalltalk/vm/products/cogspurlinuxht/lib/squeak/5.0-201606230315-firstbuild

  $ ../../../scripts/updateSCCSVersions
  $ ./mvm
clean? y
Libraries have been installed in:

 /home/ben/Repos/OpenSmalltalk/vm/products/cogspurlinuxht/lib/squeak/5.0-201606182358-secondbuild

So it seems updateSCCSVersions needs to be run *every* time I change branch
before running ./mvm.
Should it be added to mvm?
