Comment (by MarcusCalhoun-Lopez):

 There seems to be two problems here.[[BR]]
 Apparently, clang and gcc [http://stackoverflow.com/questions/21592494
 /initializer-element-is-not-constant-error-for-no-reason-in-linux-gcc-
 compilin treat constants differently].[[BR]]
 Further, newer versions of Xcode use {{{__attribute__}}} in a way GCC does
 not understand.[[BR]]
 [changeset:"7519f9aeb46b10b14cb9d36589b55664df487403/macports-ports"
 7519f9ae/macports-ports] is certainly not pretty, but does it solve the
 problem?
