Comment (by mojca@…):

 The quick-and-dirty workaround that worked was to set
 {{{
 -DCMAKE_OSX_SYSROOT="/" \
 -DCMAKE_OSX_DEPLOYMENT_TARGET=""
 }}}
 inside `cmake-1.0.tcl`. (I could probably have done the same in the
 `root6` `Portfile`.)

 The variables really need to be "set to empty", else CMake adds SDK flags
 automatically.

 Now ... the problem is that this starts building, but then fails again
 later on. I believe that ROOT tries to configure CLING as part of the
 process:
 {{{

 -DLLVM_INCLUDE_TESTS=OFF /.../ /path/to/root6/work/root-

 Re-run cmake no build system arguments

 -- Check for working CXX compiler: /opt/local/bin/clang++-mp-3.4 -- broken

 ... same error ...
 }}}
