I really do not like the smell of this.

As far as I can tell, the only real reason why you need this and
cannot use ../../bin-wrappers/git directly is because the GITPERLLIB
it gives you only points at ../../perl/blib/lib and not this
directory.

Two possible alternatives:

 - Is there a reason you would not want to "install" whatever Perl
   modules you want to "use" via GITPERLLIB mechanism to
   ../../perl/blib/lib?  Perhaps it will interfere with the real
   installation step in ../../perl/Makefile?  If that is the case,
   then it is not a good idea, but otherwise, that would let you use
   ../../bin-wrappers/git as-is.

 - Perhaps we could do:

        GITPERLLIB="${GPLEXTRA+$GPLEXTRA:}@@BUILD_DIR@@/perl/blib/lib"

   in wrap-for-bin.sh, so that your instruction can become

        GPLEXTRA=$(pwd) ../../bin-wrappers/git whatever-mw-thing

   and you do not have to have this file?  We would also need to
   "unset GPLEXTRA" at the beginning of test-lib.sh if we were to do
   this.

How does a developer (or user) use this script?  From your Makefile
(e.g. "make test")?  Manually following some written instruction?
In either case, the latter option feels a lot more sensible
alternative without having to maintain this extra copy of wrap-for-bin
that can easily go out of sync.
