I don't follow. Can you not use 'diff' and 'patch'?  I am so old that I have

   tar xvzf foo_1.2.3.tar.gz
   mv foo foo.orig
   tar xvzf foo_1.2.3.tar.gz
   cd foo
   /* now do your work */
   cd .. && diff -ru foo.orig foo > foo.patch

fairly deeply engrained in muscle memory.  And R itself is in pretty tip-top
shape and will listen to 'configure; make; make install'.  You probably can
even skip make install as you are "just" fighting a failure to build.
