Check for XCode >= 4.2 on Lion first before casing the GCC build in the install section as this is the order in which the download section selects which Lion binaries to fetch. Without this change, a leftover `gcc-4.2` installation can fool the logic into thinking the 5666-3 binaries were downloaded instead of the full GCC-4.2 suite. This causes the wrong installation steps to be executed which leaves users without some important symlinks. Closes Homebrew/homebrew#9398. Fixes Homebrew/homebrew#9395. Fixes Homebrew/homebrew#9043. |
