macports localinstall github tries to download from macports

[Ken Cunningham]

I would suggest  you try going with what the github PG wants to use for it's defaults for this moment, and see what you think of that. It's usually good.

We do prefer, if there is one, an official "GitHub Release" which sometimes has extra stuff in it, but this is your own personal Portfile right now, and you're just trying to get it done, so don't worry about that stuff for now.

If you glance at the top of the github portgroup TCL file you will read more than you could ever want to know about how the github portgroup works and what options it supports:

/opt/macports-ports/_resources/port1.0/group/github-1.0.tcl
