It would be really nice if dependencies could blacklist compilers separately for their own use and separately for software needing them. Then any port using that dependency would not attempt to use the ancient compiler / there would be no need to blacklist compiler in a recursive way to each and every user of a dependency.

This issue was fixed after we switch to libc++ on 10.8.
