My first attempt to use Porting/bisect.pl:

$ ../Porting/bisect.pl --start=v5.17.0 --end=v5.17.1 --target=miniperl -j10 -e '<some code>'
We are not bisecting.
Previous HEAD position was 9bdaae7... use ppport.h for Storable on Perl 5.8.9
HEAD is now at 955b6ac... one more place to get rid of win32/config*.gc64nox
Can't exec "ccache": No such file or directory at ../Porting/bisect-runner.pl line 526, <$fh> line 162.

That took 56 seconds

It's correctly picked up the git revisions for the start and end points
that I gave.  In both cases it's then falling over at the makedepend
stage due to making some bizarre reference to "blead".  I don't have
any git branch or tag named "blead".  --end is documented to default to
"blead", but I gave an explicit --end, and the initial switch to commit
955b6ac shows that my --end has been parsed correctly.
