Git has a very clever Makefile.  Sometimes its a little overly clever.

1) I use stow to manage my /usr/local directory.  With many other  
programs I am able to build with a prefix of /usr/local and install  
with a prefix of /usr/local/stow/$program.  Git detects a change in  
the build variables and recompiles pretty much everything.

2) If I remove the old copy of git before installing the new, git will  
notice this and again start a (smaller) recompile because the GIT- 
VERSION-FILE file changes from something detailed like  
"1.5.3.5.622.g6fd7a" to "1.5.3.GIT".

Is there a way to tell git to be a bit less clever and just install the already compiled program? If not, would changing the Makefile to read something like the following be accepted?

----- 8< -----

install: all install-dumb

install-dumb: # No rebuild!
   # Current install process

----- 8< -----

I also stow git (which doesn't come with a make uninstall grrrrrr) and what I do is that I dropped the dependency of `install' on `all'. Also, I always install the new version before removing (stow - D) the previous one.

I found a way around the Makefile cleverness. It's ugly, but it requires no changes to the existing Makefile. I'm posting it in case anyone finds this thread trying to do what I'm doing. My nieve suggestion fails, BTW, because git-gui's Makefile does the same cleverness.

# Install ignoring version changes, etc. ignore="-o GIT-VERSION-FILE -o GIT-CFLAGS -o GIT-GUI-VARS" install="$ignore prefix=/usr/local/stow/git" gitgui="$install gitexecdir=/usr/local/bin" sudo make $install NO_TCLTK=Yes install install-doc sudo make $gitgui -C git-gui install

Why do I have to go through so many hoops just to install what I've already compiled?
