First things first - development of phobos is done with dmd. Just 
because gdc is (logically so) somewhat behind dmd and new compiler 
features are still coming with every release.

The process usually involves git cloning dmd, druntime and phobos.
Then building all of them in the order of dmd, druntime, phobos.
The the tricky part is replacing older binaries and library.

After fresh cutting phobos edge builts make sure Phobos unittests all 
pass (make -fposix.mak unittest).
I suggest to just modify phobos sources directly. It's DVCS after all so 
you always have a luxury of commit/revert.

and rdmd --main -unittest /path/to/std/random.d
works wonders in development cycle.
