 Hi,

 The attached update bumps the ROOT port to 5.34.10.

 It also reworks the gcc variants to address issues with mixing c++
 runtimes, by no longer using these variants to set the c/c++ compilers.
 They are now only used to set the fortran compiler.

 The cocoa variant is now update to use compiler black and fall back lists
 to make sure a compatible clang compiler is always used. (Can only test on
 OSX 10.8 with Xcode 4.6.3 so rely on reports from others for problems with
 other combinations).

 cheers Chris
