wait
so if you specify clang for lhapdf AND use clang as cpp compiler in amcatnlo, i think you should also specify 
CFLAGS="-O -stdlib=libstdc++ -mmacosx-version-min=10.6"
when you configue…

otherwise, if yo also have the gnu compilers (g++ and gcc) and compile lhapdf with it, you should also specify the same compiler for amcatnlo…
let me know,

Marco
