New description:

 Configure fails with xcode clang in /usr/bin/clang -> Apple LLVM version
 8.1.0 (clang-802.0.42).

 My $PATH exports first /opt/local/bin but port defaults to /usr/bin.

 Only help was to edit Portfile and comment out all supported compilers
 except gcc8 {macports-gcc-8}, put
 {{{
 compiler.blacklist-append *clang*
 }}}
 and add
 {{{
 compiler.fallback macports-gcc-8
 }}}

 Configure runs fine with gcc8.

 I didn't try other methods. This was my first idea.

 Thanks!
 -Michael
