 Could you please update the llvm and llvm-devel ports to add the configure
 args --disable-assertions and --disable-expensive-checks? Albert Graef,
 the author of the [http://code.google.com/p/pure-lang/ Pure language]
 which uses llvm, [http://groups.google.com/group/pure-
 lang/browse_thread/thread/ba59bb593bf5cec7#msg_22e236e0acb42487 says these
 options are beneficial]:
