Trying to build clang-3.5 with Xcode 7.0.1 (Build version 7A1001) on OS X El Capitan 10.11 (15A284) fails:

$ sudo port install clang-3.5 \\ ---> Computing dependencies for clang-3.5 \\ ... \\ ---> Building clang-3.5 \\ Error: org.macports.build for port clang-3.5 returned: command execution failed \\ Please see the log file for port clang-3.5 for details: \\ /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_llvm-3.5/clang-3.5/main.log \\ ...\\ Error: Processing of port clang-3.5 failed \\

This seems to be a linker problem related to libc++, as the log file repeatedly contains the lines:

:info:build ld: library not found for -lc++ \\ :info:build clang: error: linker command failed with exit code 1 (use -v to see invocation) \\

BTW: Building clang-3.6 on the same system works without a problem.
