[Buildbot-devel] shellcommand cd problem

I suspect that it's failing to find a 'cd' command.  For it to work at all,
cd has to be a builtin of the shell and so is not directly executable.  What
I tend to do with bb is use utility scripts that assume they're working in
the root of the checkout.  I.e. the script reads:

  cd src
  do something
  do something else

or you could use a utility Makefile that simply cd's to src and reinvokes
make in that directory

Does that help?
