How does gdc know where to look for druntime/phobos source code? I successfully built gdc for the first time on OS X, but it's looking at completely the wrong source code.

I have gdc manually (i.e. make install) installed in /opt/gdc and ldc installed via homebrew in /usr/local, but when I try and compile anything with gdc I get

/usr/local/Cellar/ldc/0.15.2-beta1/include/d/core/stdc/config.d:28:3: error: static if conditional cannot be at global scope
   static if( (void*).sizeof > int.sizeof )
   ^

which makes very little sense to me. At the very least I would have expected it to see /usr/local/include/d or /usr/local/include/d2

That's really strange. This code handles include paths: https://github.com/D-Programming-GDC/GDC/blob/master/gcc/d/d-incpath.cc
