Note that a `git fetch' isn't sufficient, that won't update the 
working tree.  `git pull' is the most commonly used command to keep 
a git tree up to date with some upstream.


As for building: if you need the build to work every time then you 
need to clean out the entire build tree and start from scratch 
every time (e.g. with the `git clean' command).

If you're willing to trade correctness for speed you can do:

   make && make install

 if that fails:
   ./config.status && make && make install

 if that fails:
   git clean -dqffx && ./configure <args> && make && make install

 if that fails:
   report bug
