The ebuild of dev-util/pkgdiff uses the variable ${D} during the src_install() phase. I tried to emerge this package inside a Gentoo Prefix. Trying to install it to ${D} naturally caused failure since we cannot install it outside the Prefix. I think maybe we should change ${D} to ${ED}.

Created attachment 639598 [details, diff] patch with dodir to create ${PREFIX} a patch to make mkdir work properly
It still failed, because it did not create ${ED}/${PREFIX} properly. Maybe `dodir` will help to prevent this situation?
