The mariadb build failures are easy: they're failing because strnlen is not defined. This is correct: strnlen was not part of OS X until 10.7. You should report this problem to the developers of mariadb. They need to either avoid using strnlen, or else provide an implementation of it when the OS does not.


The gcc build failures are unfamiliar to me:

I don't know what these errors mean but I see MacPorts has decided to build with clang. The port blacklists llvm-gcc42, so I assume this means you are running Xcode 4. (Xcode 3.2.6 is recommended for MacPorts on Snow Leopard.) It's possible the old version of clang in Xcode 4 on Snow Leopard is insufficient to compile this code. You could try compiling with a newer MacPorts clang compiler:

sudo port clean libgcc
sudo port upgrade libgcc configure.compiler=macports-clang-3.4

If that works, we can adjust the port's blacklist to exclude the older clang.
