Comment (by rmottola):

 @neverpanic I specified "without further patches", so it was out of the
 box. Just noticed a newer version of MacOS 10.11
 By applying the PR it compiled (don't know ho actually test it)

 The reason why it works on 10.7 is quicky explained: it uses binary
 packages. So on the build server it did compile?
