I'm trying to install qtcore in my prefixed environment. It failed during the installation phase:

The problem here is that qconfig.pri is not there but at /home/evidgbo/usr/roots/gentoo/var/tmp/portage/dev-qt/qtcore-5.9.4-r1/image/home/evidgbo/usr/roots/gentoo/usr/lib64/qt5/mkspecs/qconfig.pri. Ie. $EPREFIX/var/tmp/portage/dev-qt/qtcore-5.9.4-r1/image/$EPREFIX/usr/lib64/mkspecs/qconfig.pri instead of the one which misses the EPREFIX in the middle of the file path. This is correct in my opinion.

After a short debugging I fixed the problem in qt5-build.eclass's qt5_install_module_config(), at the very end, by replacing ${D} with ${ED}, like this:

        set -x
	# install also the original qconfig.pri
	[[ ${PN} == qtcore && ${QT5_MINOR_VERSION} -ge 9 ]] && (
		insinto "${QT5_ARCHDATADIR#${EPREFIX}}"/mkspecs/gentoo
		declare -p D QT5_ARCHDATADIR EPREFIX
		newins "${ED}${QT5_ARCHDATADIR#${EPREFIX}}"/mkspecs/qconfig.pri qconfig-qtcore.pri
		newins "${ED}${QT5_ARCHDATADIR#${EPREFIX}}"/mkspecs/qmodule.pri qmodule-qtcore.pri
	)
        set +x

Here's the debugging output:

Emerging rest of the @world seems woring fine since then.

I think it's just not supported...

Why do you think so?
