I have a working prototype of this, and it handles checking out the correct 
branch each time the spell is cast. However it does not provide any locking 
for the case where the repository is shared by multiple machines, as this 
does 
not yet apply in my case.

DETAILS:
# make spell git-able
GIT_ABLE=yes
. $SPELL_DIRECTORY/FUNCTIONS
           SPELL=boost
         VERSION=git
          BRANCH=1.41.0
          SOURCE=$SPELL-$VERSION
SOURCE_DIRECTORY=$BUILD_DIRECTORY/$SOURCE
   SOURCE_URL[0]=git://gitorious.org/boost/cmake.git


FUNCTIONS:
# support for git-able spells
# we keep the repository in $SMGL_GIT and make a symlink to it when building
if [[ $GIT_ABLE == yes ]];then
SMGL_GIT=/var/git
# don't need the archive or docs, as they are readily available in the 
repository
ARCHIVE=off
GATHER_DOCS=off
fi

default_git_download() {

if [[ ! -d $SOURCE ]];then
  git clone $SOURCE_URL $SOURCE
else
  cd $SOURCE &&
  git pull
fi

}
