--------------------+-----------------------------------
 Despite the best efforts of the post-configure phase to patch in the path
 to the correct compiler, the build still invokes `cc`:

 {{{
 :info:configure --->  Patching Makefile: s|^(CC *=).*|\1 /usr/bin/clang|
 [...]
 :info:build cc -fPIC -O2  -Ic/include \
 :info:build         -c c/common/dictionary.c -o
 bin/obj/c/common/dictionary.o
 :info:build cc -fPIC -O2 -Ic/include -c c/common/dictionary.c -o
 bin/obj/c/common/dictionary.o
 :info:build cc: Error: You should be using ${configure.cc}
 :info:build See https://trac.macports.org/wiki/UsingTheRightCompiler
 :info:build gmake[1]: *** [Makefile:42: bin/obj/c/common/dictionary.o]
 Error 1
 }}}

 (It fails because my installation is configured as per
 UsingTheRightCompiler#testing.)
