Indeed, sourcing additional files is incompatible with storing the
Portfile in the registry. Don't do it.

pre-checksum would be run in a deeply nested context inside the port1.0
module. This is an implementation detail and Portfiles should not rely
on that. If you need to modify state outside of the proc, use a "global"
variable.
