The name matching condition is my problem with this approach, which is
why I was looking for a way to do specify a local source in the package
definition itself.

I am working in the Python universe where package names almost never
match the name of the checkout directory because of the python- prefix.
Moreover, I want to build both python- and python2- packages from my
checkout.

None - once I import (guix gexp)  ;-)

Thanks,
