 libvpx fails to build if dev tools are installed outside /Developer. That
 says it all, basically (using 10.6.6, BTW). It fails during configure,
 here is the relevant part of the log:
 ...
 Darn, the error log is gone now that I've been able to build it correctly.
 Anyway, the configure check for pthread.h failed, because the compiler was
 invoked with -isysroot /Developer/SDKs/MacOSX10.6.sdk .

 I do not install any variant of the dev tools in /Developer these days,
 because between the iOS SDK version, the version for Mac development only
 (the iOS SDK variant has from time to time bugs that prevent "real" Mac
 development), Xcode 4, and the prerelease versions (which one must install
 alongside the shipping ones since one cannot build App Store apps with
 them), there is no longer a canonical version that should go in
 /Developer. I wonder why a Unix dependency management system needs to look
 in the /Developer domain anyway.

 Workaround is to create a symlink in /Developer/ (this folder nevertheless
 exists for CHUD) called SDKs to <wherever I installed the Xcode for Mac
 development>/SDKs.
