github & url2pkg

[mlh%goathill.org@localhost (MLH)]

I was hoping that url2pkg would understand more github projects
and wanted to try to bring in goldencheetach via
https://github.com/GoldenCheetah/GoldenCheetah/archive/v3.5-DEV1710.tar.gz
but it still misfires on building the url:

 Can't lookup
 `v3.5-DEV1710.tar.gz:https://github.com/GoldenCheetah/GoldenCheetah/archive/DEV1710.tar.gz':
 servname not supported for ai_socktype

I can't find instructions or examples to understand how one is
supposed to set variables to build the url correctly for a case
like this.

The url2pkg bare Makefile:
