all the standard MacPorts compilers (gcc versions, clang versions) support the -faltivec flag.
This flag is only useful on PowerPC systems, which I would be surprised if you were targeting. Is that the system you're after? The fact that it's still in the config suggests this is a very old piece of software. BTW, for practical purposes, only gcc versions offer useful PowerPC code generation at present.
