------------------------+--------------------
 Based off of https://github.com/dbanay/Smalltalk/ I have created a
 Portfile that is 90% of the way there.

 In its current state: it will fetch the source, and build a binary, all
 well and good.

 However, it fails during install because the Makefile from the upstream
 project is so sparse, it does not have an install to make! (Nor an "all"
 to make for that matter, but that is at least something which can be
 worked around a bit with build.target thanks to MacPorts and markh and
 khindenburg_ on IRC for helpful suggestions!)

 Anyway, perhaps the best way to address this is to patch the Makefile?

 Maybe someone else has a better approach?

 Probably there is a better way to "version" this as well (I am just using
 the most recent git branch tag since there are no "release" nor "version"
 nor tarball to reference presently), maybe HEAD? I am open to suggestions
 for improvement!

 I figured I would share the progress I have made thus far to at least get
 it off my local system, but additional effort is required to get this into
 a state which merits a PR.
