OSX 10.8 xcrun (No such file or directory)

Unfortunately, at least the last time I played with it, I found you really can't use xcrun with just the standalone Command Line Tools package. It apparently wasn't designed for that use case; the standalone package is a fairly recent innovation with Xcode 4. If the product you are trying to install really depends on xcrun, you may need to install the full Xcode.app distribution to get around it. That, or modify the distribution's Makefile et al to not use xcrun. Or, possibly (untested), create some directories and/or symlinks to fake xcrun into thinking you have Xcode.app installed - a messy hack.

Type in these commands on the console:

sudo xcode-select -switch /usr/binsudo mv /usr/bin/xcrun /usr/bin/xcrun-origsudo vim /usr/bin/xcrun

Enter the following into your dummy xcrun file:

#!/bin/sh$@

Then make it executable:

sudo chmod 755 /usr/bin/xcrun

Even with Command Line Tools installed, your xcode-select is strange. It should be pointing into your XCode bundle, not /usr/bin:

$ xcode-select -print-path/Applications/Xcode.app/Contents/Developer

Switch it to Xcode like this:

$ sudo xcode-select --switch /Applications/Xcode.app
