  The fact is that ml_gtk (labelgtk2) depends on the libraries built 
beforehand. e.g:

$ otool -L /opt/local/lib/ocaml/site-lib/stublibs/dlllablgtk2.so
  … tons of libs

$ otool -L /opt/local/lib/ocaml/site-lib/stublibs/dllivy-ocaml.so
/opt/local/lib/ocaml/site-lib/stublibs/dllivy-ocaml.so:
        /opt/local/lib/libivy.dylib (compatibility version 0.0.0, current 
version 0.0.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current 
version 1213.0.0)

  if you move to a newer Xcode (command line tools), 

$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr 
--with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 7.0.0 (clang-700.0.72)
Target: x86_64-apple-darwin14.5.0
Thread model: posix

  then you have to re-compile all dependents (by hand, homebrew, or macports)

  With regards to gcc-arm-none-eabi, I think that the one that’s known to work 
with ppz is the one provided with ubuntu (4.9.3.2014q4-0trusty12). Macports 
provides arm-none-eabi-gcc              @5.1.0 , I don’t know if it’s reliable.
