Comment (by daniele.tartarini@…):

 Thanks for your prompt reply.
 in my machine /usr/bin/c++ is a symbolic link to /usr/bin/clang++ (Apple
 LLVM version 7.3.0 (clang-703.0.29))

 I have not modified the configuration files.
 Please find attached the main.log with the clean install as required.

 looking forward to solve

 Replying to [comment:3 devans@…]:
 > It looks like your compiler is configured incorrectly, that is,
 something is overriding the ports default compiler settings.  Your build
 uses /usr/bin/c++ but should be using /usr/bin/clang++ and the expected
 flags -std=c++11 -stdlib=libc++ appear to be missing.
 >
 > I can't tell how this is happening because your log is not from a clean
 build and does not show what happened during configure.  Have you made any
 customizations of the port or the configure/build environment variables
 that might be causing this problem?
 >
 > Please execute the following commands and attach the resulting log which
 should show the configuration phase as well as the build phase up to and
 including the build failure.
