oh damned.
i thought "-framework bla" was a compiler-flag, and not a linker-flag.
this explains why the compiler bails out.

hmm, this means that the check for compiler-flags seems to not work 
correctly
"-ip -ipo_obj" are flags for the icc vectorizer; GEM_CHECK_CXXFLAGS() 
should test whether the compiler is able to manage these flags, and if 
it does not fail, they are added to the CXXFLAGS.
what does configure say when it comes to checking these ?

on my debian x86 using g++, it says:
   checking whether compiler accepts "-ip -ipo_obj"... no

you should get the same....
