Fun.
I am getting this (probably unrelated to this patch), by the way:
$ make perf
make -C t/perf/ all
make[1]: Entering directory `/srv/project/git/git.git/t/perf'
rm -rf test-results
./run
...
perf 4 - grep --cached, expensive regex: 1 2 3 ok
# passed all 4 test(s)
1..4
Can't locate Git.pm in @INC (@INC contains: /etc/perl ...) at ./aggregate.perl line 5.
