Seb,
Thanks for responding.  Are these the instructions for building from git for 
the current 2.5 branch?  How do I apply the patch?

git clone git://git.linuxcnc.org/git/emc2.git emc2-dev
git branch --track v2.5_branch origin/v2.5_branch
git checkout v2.5_branch
$ cd src
 $ ./autogen.sh       
 $ ./configure
 $ make 
 $ make install-menus
 $ sudo make setuid
