arm-elf-gcc missing zlib dependency

[hannes@…]

Macports failed to install arm-elf-gcc by itself, after installing zlib everything worked fine.

The -L../zlib indicates it's actually trying to link against its own internal copy if zlib. Also, where did /opt/local/lib/libz.dylib come from if not the zlib port?

[jmroot (Joshua Root)]

Does this still happen with 4.6.1?

[raimue (Rainer Müller)]

Probably fixed by updates, arm-elf-gcc is now at 4.7.3. If it is not fixed, please reopen.
