It may run but it won't compile. I'm no fan of Gentoo, but if it's open source I ought to be able to reproduce the binary with those sources.
Edit: An open source program must never depend on binaries in the build process where those binaries can't themselves be rebuilt from source. Again, I'm not a zealot but as a developer I see dependencies on arbitrary binaries as damage and try to work around them.
