Are you sure about that?  Try adding something like

  die("I am broken");

at the very beginning of main() in git.c, rebuild your git (i.e.
"make", not "make install")
and then

  $ cd t
  $ sh ./t1234-test.sh -v

for any of the test scripts. You should see any test piece that runs "git" sees
"git" dying with that message.

Otherwise, there is something wrong with git you are building. Unless you have
a patch or two to t/test-lib.sh or something that breaks the test framework, you
should be able to test what you just have built without getting affected by what
is installed in your $PATH. After all, that is how we bootstrap git
from a tarball
without any installed version, and friends do not force friends install without
testing first ;-)
