Thanks guys, will be pushing a fix shortly.
As Cygal has pointed out, git is quite different to svn, there are no sequential revision numbers, git calculates a hash to identify all commits, while these are long the first 6 or so digits should be sufficient to identify a commit.
So, at time of writing, head (refs/heads/master) is currently at commit 'eee8ac...'
If you have just done git pull then get a compile error, just saying you're on 'head' would also be fine.
Cheers.
Edit: Fix is in (and head of master is now at 4da367b..)
