Like I say not exactly an expert. But it looks like when run in this
manner 'git pull' is unable to figure out the location of the .git
directory. Try something like.

system("GIT_DIR=$data_path.git; git pull");

There were some other replies to your original post that promising for
the cc-to-git-and-back aspect. Looking into them may save you a lot of
time.

Good luck.
