- Fix link error with clang Fix a link error with clang & libtool. Configure chooses --export-dynamic but that flag doesn't normally start with two dashes, only one. There are no overrides or switches available for that. The fix is an inline patch for configure, adding the compiler case for darwin*) to set ZZIPLIB_LDFLAGS="-export-dynamic". Add the inline patch and bug report url to the formula. Add the 2sec make check for this compression library. Checks on Lion 10.7.3 and SL 10.6.8 with all five compilers from the 4.3 CLT and XCode-4.0.2 (4D502). Closes Homebrew/homebrew#10672. Signed-off-by: Jack Nagel <jacknagel@gmail.com>
