mingw-w64-gcc is the only mingw-w64 package you want to makedepend on, maybe consider to depend on mingw-w64-crt.

You've still got references to OS X and windows installs
Also instead of
if test _arch == '32'; then scons -j $cores platform=server target=release_debug tools=no bits=32 else scons -j $cores platform=server target=release_debug tools=no bits=64 fi
you can just do
scons -j $cores platform=server target=release_debug tools=no bits=$_arch
You're setting _arch in 3 places even though it can only have 2 values; it's also in an array for no apparent reason, you can shorten it to _arch=32 [[ $CARCH == x86_64 ]] && _arch=64
Or some such variation.
The same goes in the install, you have a bunch of 'if _arch == 32' and then using 32 twice in a string; just substitute that with the variable.
