Comment(by ryandesign@…):

 The compiler selection block seems very confused. What you've written is:

 {{{
 if {${configure.compiler} == "clang" ||
     ${configure.compiler} == "llvm-gcc-4.2"} {
     configure.compiler clang
     if {![file executable ${configure.cc}]} {
         depends_build-append port:apple-gcc42
         configure.compiler apple-gcc-4.2
     }
 }
 }}}

 What this is saying is: If the compiler is clang or llvm-gcc-4.2, set the
 compiler to clang, and if that does not exist, then use the apple-gcc-4.2
 port.

 I think what you did was take a block that was meant to ensure the use of
 gcc-4.2 on systems that would otherwise use llvm-gcc-4.2 or clang, and
 modified it. As written, the [comment:4 original block] made sense:

 {{{
 if {${configure.compiler} == "clang" ||
     ${configure.compiler} == "llvm-gcc-4.2"} {
     configure.compiler gcc-4.2
     if {![file executable ${configure.cc}]} {
         depends_build-append port:apple-gcc42
         configure.compiler apple-gcc-4.2
     }
 }
 }}}

 This says: If the compiler is clang or llvm-gcc-4.2, set the compiler to
 gcc-4.2, and if that does not exist, then use the apple-gcc-4.2 port.

 For arb, I think what you want to write is quite simply:

 {{{
 if {${configure.compiler} == "llvm-gcc-4.2"} {
     configure.compiler clang
 }
 }}}
