compilation process stuck on OS X

[lhatsk]

OS: OS X 10.8.5
I was able to compile rust on 8-9-2013.
The problem seems to be twofold:
After upgrading the command line tools to xcode 5 (september '13) and executing

git clone https://github.com/mozilla/rust.git && cd rust/ && ./configure

configure is stuck at: configure: CFG_CCACHE with xcrun running at about 90% CPU utilization. I killed it after about 10min- rerunning it doesn't change anything.
I then installed xcode462_cltools_10_86938259a and was able to run ./configure successfully. The compilation process progressed up until libuv and was stuck again with xcrun running at about 90% CPU utilization. I killed it after 50min.
In the end I was able to compile rust after doing

sudo xcode-select -switch /usr/bin

The problem seems to be caused by a misconfiguration, but still, xcrun shouldn't just block (infinitely(?)).

I have just run into this problem too. Running sudo xcode-select -switch /usr/bin fixed it for me.

We've been compiling on OS-X / XCode 5 for a bit now, so I'm going to close this ticket. If you see this again, please file a new bug. Thanks!
