I believe git should clone into the DL_DIR once, and only once (unless
of course you delete it from DL_DIR.)  I say this because it is source
regardless of the particular tool used to keep track of it.  Then, just
soft link to it's location in the DL_DIR from the build dir. (see also
below)

Why would you want to do that?  You wouldn't keep downloading a tarball
once it is downloaded. Once you've cloned a repository you don't need to
do it again unless you really screw things up.  What would be nice in my
opinion is if there was an option for which commit to use with one
option being "latest" which would 'git pull' first to build the latest
version.
