Comment(by vinc17@…):

 With the above change, texlive-bin can be compiled and works. But since
 some programs are written in C++, perhaps CPLUS_INCLUDE_PATH should be
 used too. I didn't see any error, but it is still possible that a header
 file from /usr/include had been used instead of the one from
 /opt/local/include. An incompatibility may yield build-time or run-time
 failures.

 Note that if you want a single environment variable, CPATH could be used
 (as it is language-independent), but C_INCLUDE_PATH and CPLUS_INCLUDE_PATH
 are more robust than CPATH, since CPATH is more like -I than -isystem.
 This means that CPATH would be ignored is a MacPorts version of cpp is
 used, as ${prefix}/include is a system directory in such a case (however,
 since ${prefix}/include comes first, it would still have the precedence
 over /usr/include, and everything should be fine).
