I was looking around to see if there was an alternate perl
implementation and I ended up packaging micropython. I have no
preference between it being in python.scm or embedded.scm

Hi Erfraim,

Heh :)

There's a bundled version of FreeRTOS in ./ports/cc3200 which is GPLv2
with a modification.

In this case, I suggest to delete FreeRTOS since we don't use it
anyway--and if we ever wanted to, we'd not use the bundled version.
So in a sense I suggest to unbundle it.

We could also just add GPLv2 with exception to the license list,
but in this case I wouldn't--since it doesn't really apply to the
installed version and we don't use it anyhow.

Also, there's a bundled copy of libffi in lib.  Usually, I delete
it to make sure it's not picked up by accident.

Otherwise LGTM!

I'll go ahead and remove it.

Looking at the .gitmodules¹ it looks like there's a number of bundled
librarires in the lib folder. With all of them removed it no longer
builds. Looks like I need to take another look at it.

I also switched python-minimal-wrapper -> python-wrapper

“python.scm” seems fine.

Oh, this Python needs Python…?  I think you should be using
python-wrapper here as the python-minimal variants are merely supposed
to be used for breaking a cycle in the build of Python itself.
