When you use github.setup, a tarball is fetched directly from the
GitHub server, without resorting to git in any way, and works as if
you fetched the sources from elsewhere.

When you use git directly, the checksums are (sadly) not yet verified.
If you fetch from a particular commit in git, the shasum should
usually give you sufficient reliability (to some extent), while if you
use master (or any other branch for that matter), you would not get
reliable contents anyway, and it's highly discouraged to fetch from a
branch as you never know what could break and when.

This is admittedly suboptimal. Rainer did some 80% of the work, see
or the corresponding branch (vcs-fetch) in macports-base, but he might
need a push to complete the work, test and merge the code :) :) :)

I recently stumbled into a wall myself when trying to do something
less conventional with patch files [1]. I ended up running patch
manually which is heavily suboptimal and it could help to modify the
base a bit to better support a scenario of having an extracted patch
file somewhere or the disk that's not exactly files/, but I don't know
what exactly you scenario is. MacPorts would happily support applying
a patch from a .bz2 file located somewhere online, for example. Where
did you get the patch file from / how?
