I'm trying to build something that RedHat wrote for Linux on a Mac Book Pro running OS X 10.4.8, and have come across a need for a file called byteswap.h, which appears to be a Linux-only thing.
I imagine that at least one of the mac ports have run into needing a version of this file.
I could invent an empty version of the file, and then fill it up with whatever the build can't find. Is this file particularly well defined?

I don't know the answer, but for questions like this I usually see if there is a FreeBSD port for the app in question to see how they dealt with it. FreeBSD is very similar to OS X and they have to overcome Linuxisms too. They frequently have patches that can be used unmodified for MacPorts, or if not their patches give clues as to how a patch for MacPorts can be made. http://www.freebsd.org/ports/ I've also keep an eye on Portage patchfiles for the same reason. http://mozilla.mirrors.tds.net/pub/gentoo-portage/ If no one answers your question directly, perhaps the issue has alredy been dealt with in other package managers and you can learn from that.
