You need to set DESTDIR="${D}" when you pass --prefix="${EPREFIX}"/usr
(or equivalent), otherwise, you will install files to
${EPREFIX}/${EPREFIX}/usr. As Prefix expects files in ${EPREFIX}/usr,
etc., this will cause issues on all Prefix systems (specifically,
Portage will error out if it detects any file installed into $D that is
outside of $ED or the directory $ED/$EPREFIX existing at all (when
$EPREFIX != "")).
The only time that it is generally appropriate to set DESTDIR="${ED}" is
when dealing with broken build systems that force a prefix of exactly
"/usr" and don't allow the user to change it (or even force files into
"/bin", "/etc", etc.).
