Comment (by ryandesign):

 That's what I thought. Why did we do it that way? It is very confusing. I
 don't want to modify `bin_path` on the buildbot workers because I am
 concerned that this will affect how some ports build.

 I was going to ask why we didn't do it the way we handled parallel bzip2
 support, but now that I've looked at it, we've handled that in a very
 confusing way as well. We allow the user to specify a bzip2 at configure
 time, which could be a parallel bzip2 such as lbzip2, but it looks like in
 many cases we ignore the user's request and choose a program from the path
 instead.

 I feel that we should let the user specify these programs via configure
 args and if the user has done so we should always honor that request. If
 the user hasn't specified something, then we can choose what we think is
 best.
