 Missing are

 {{{
 000000000000039e T _clang_CompileCommand_getMappedSourceContent
 0000000000000345 T _clang_CompileCommand_getMappedSourcePath
 0000000000000326 T _clang_CompileCommand_getNumMappedSources
 }}}

 They are missing from libclang.exports file.
 ${SRC}/tools/clang/tools/libclang/libclang.exports

 Can MacPorts patch that file so that symbols are correctly exported to the
 shared library?
