Building from git on OS X

[Geert Janssens]

I am at a point I'd like to test my gsettings work on Windows 
and OS X.

For Windows I can be short: I can build my private gsettings 
branch just fine, but no settings are saved or restored :( 
Investigation is ongoing.

I now want to run the same test on OS X. I have been looking 
at the instructions again to build on OS X. It allows to build 
gnucash-stable, gnucash-unstable and gnucash-svn. However, 
my changes are in a local git repository. How can I use that one 
to build from ?
