git-core stalling during build

[Lee Bast]

Good day all,
	I've always had git-core +svn installed and running on this system immediately after every major upgrade. When I last tried to update to the 1.8.2 branch however the process stalled out during build. It doesn't fail with an error message, it simply reaches a point and then stops making any progress, CPU usage goes to zero, and it'll hang there indefinitely until halted.
	I stayed on 1.8.1.3 until the latest 1.8.2.1 to see if it was something temporary, then I tried completely uninstalling my old version of git, cleaning, and then installing from scratch. No dice, stalls at the same place every time, so it now won't install at all. Every other port functions normally, and other existing ports can be upgraded and new ports installed without issue. I'm running MacPorts release 2.1.3 (daily selfupdate), 10.8, and Xcode 4.6.2 with latest CLI tools. I'm able to install it on another Mac Pro (running 10.7) and it worked fine on 10.8 up until now, so it's likely specific to this system.
	The last few lines before it stalls are here, full log attached:

> 	 echo >>lib/tclIndex ; \
> 	fi
	I'm at a bit of loss here since I can't get it to repeat anywhere else. I was thinking of just nuking MacPorts and reinstalling everything from scratch, but before that I wanted to check if anyone had any ideas about a more elegant solution. I don't know if there could be corruption somewhere in my tree or how to check for it or any similar lower level troubleshooting, mostly because I've never really had occasion to over the course of nearly a decade, which is a testament to MacPorts' overall reliability as much as anything. Any thoughts would be appreciated.

Thanks for your consideration,
Lee
