Problem compiling: that perl thing again

Over the last 2 months each time I pull, check out next and compile,
I'm seeing _some_ kind of problem with compiling the perl section
of git.  Sometimes git-reset --hard, or a fresh checkout, or git-clean
resolve the situation.  But not this time.

Here is what I see now:
$ make
...
make -C perl PERL_PATH='/usr/bin/perl' prefix='/home/luben' all
make[1]: Entering directory `/home/luben/projects/git-next/perl'
Makefile out-of-date with respect to Makefile.PL

$ git-rev-list --max-count=1 HEAD

So, where is "perl.mak"?
