what is a correct way to build ports with clang

[Volodymyr Kostyrko]

Hi all.

I recently stumbled upon minor inconsistency when building misc/mc. The 
build goes well when CPP is unset or when CPP=clang -E, but fails when 
CPP=clang-cpp:

/tmp/ports/usr/ports/misc/mc/work/mc-4.7.5.5/config.log:

configure:23603: checking for slang.h
configure:23618: clang-cpp -ltermcap -I/usr/local/include 
-I/usr/include -L/usr/lib conftest.c
Stack dump:
0.      Program arguments: clang-cpp -ltermcap -I/usr/local/include 
-I/usr/include -L/usr/lib conftest.c
1.      Compilation construction
2.      Building compilation actions
configure:23618: $? = 139

What is the correct way to build ports with clang? Wiki states that CPP 
should be set to clang-cpp for everyone however this doesn't work here.
