Hello all, libomp still fails to build as a dependency of clang 3.8 installation as shown in Step 4:
main.log from /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_libomp/libomp/ http://pastebin.com/9YwFQusZ This is earlier than Step 8 that was modified by Jeremy. How do I work around this error?
