 > It appears that an option for that has not yet been added to MacPorts. I
 filed #18426 for this request and will commit a fix in a moment, but you
 should not use it in a Portfile until MacPorts 1.7.1 is released. Until
 then, manually do what setting configure.compiler does -- set
 configure.cc, configure.cxx etc. as needed.
 The portfile creates gcc, g++, cc and c++ executables. No apple-
 pre/postfix is added on and I don't know how that would be done.
