hello there i failed to install common lisp on osx 10.9.3, the returned error is about clang

":info:build clang: error: unknown argument: '-R/opt/local/lib' [-Wunused-command-line-argument-hard-error-in-future]"

export ARCHFLAGS="-Wno-error=unused-command-line-argument-hard-error-in-future"

but nothing works.
