If your build directory never has any source changes or new commits,
then pull is the right thing to do.  You might want to use 'git pull
--ff-only' to guarantee that your build directory is not creating
merges unexpectedly.

You did not provide enough information to help figure out why your
pull is failing to achieve the results you expect.  I suggest you
perform the pull manually in your build directory.  If it fails, git
should tell you why.  If it reports success but actually fails, you
can post a detailed explanation of the problem here so someone can
suggest the cause.
