Installing Vim 7.3 beta on Mac OS X 10.6.4 Snow Leopard

If you don't have Mercurial you can download it from:

$ hg clone vim
$ cd vim
$ hg update vim73
$ CONF_OPT_RUBY=--enable-rubyinterp make
$ src/vim --version
$ sudo make install

Note: if you decide to rebuild with new build settings it is not enough to do make clean; you must actually do make distclean in order to force configure to be re-run and pick up the new settings
