At this point, the above is just a warning that curl-config is not in your path. If curl is not installed on your system, you need to set NO_CURL=1.

Fixed by setting NO_OPENSSL=1.

git's configure script is a little different from the configure scripts in other projects. All configure does in git is set variables that are used by the Makefile. Using its rules, it tries to figure out what the best setting is for each variable. Any of these variables can be set manually in the user's config.mak file. Apparently, additional variables need to be modified from their default to handle your system. Once you determine the set of variables that need to be set, they most likely will not need to be changed when compiling future versions of git.

The above two variables (NO_CURL, NO_OPENSSL) will likely fix the errors that you reported, but I don't guarantee that more errors will not be produced and will require additional settings. All of the variables are described in the comments at the top of the Makefile. It's an iterative process. You could also use the config.mak.autogen as the baseline for you config.mak file.
