Binary installation
Since LibreOffice is such a large package to compile it is also offered in pre-compiled binaries.

The binary packages are compiled such that they fit to the libraries of a stable Gentoo system. You will encounter difficulties if you try to use them on an ~arch system; this is not supported.
