If reporting this issue please do so at (not Homebrew/brew or Homebrew/core):
https://github.com/plu/homebrew-pxctest/issues

the failure seems to be happening due to the following line in module.modulemap of CommonCrypto.framework

module CommonCrypto [system] {
    header "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/CommonCrypto/CommonCrypto.h"
    export *
}

I have few versions of Xcode installed and none of them is in Applications folder. Changing the path to my Xcode location fixed the problem. Not sure how to fix it for any Xcode location.
