That's obviously a bug in the ebuild because you should never need to install dependencies on your own -- that's a big part of what the ebuild is supposed to do. Because gentoo compiles most packages from source, all of the development files are included with the main package (including glibc) unlike most linux distros that do package them separately because many linux users are not going to compile anything. It's true that the gentoo glibc package might have omitted some of the headers by mistake, but I don't think so in this case because I just wrote, compiled, and ran a C program that includes byteswap.h and got no errors. The bottom line is that the ekopath package is broken -- for reasons I don't know, but the package maintainer should ;)
