Comment (by quest@…):

 That makes sense, but if you do it as a separate port, would it be locked
 on a particular SHA, or would it just build the latest within the go 1.2
 branch? Seems the issue the maintainer brought up on code.google.com still
 wouldn't be addressed. The package could change whenever someone commits
 to that branch.
