Compiling git

[Ken Cunningham]

Ah, you want to do something special that the port  doesn't currently offer.

I read in the install document that doing a profile build of git is felt to add only a tiny amount of extra performance...

Anyway, it does not appear that macports git port offers this at present.

Unless you have some skills in what would be mildly tricky Portfile writing, you'd either need to ask someone to do it for you (put in a trac ticket with the request) 

-OR-

use macports to do some of the work, by running a configure-only phase, then run your profile component yourself from the portsrcdir, then finish off a modified build phase to include the profile phase and let macports finish it off for you.

This is tricky to do, and so I'm being purposefully a bit vague -- if what I described makes sense to you, it could probably work.

But I'm not sure there is a lot of point, given the minimal benefit mentioned...
