Please check whether the use of 'einstall' in this ebuild is actually needed. From a quick glance at the Makefile, it seems to have proper support for DESTDIR. Therefore, if possible please replace the call to 'einstall' with proper 'default' or 'emake DESTDIR="${D}" install'. Thanks.
commit ffadee993624977fe14ae5efa4abe4ee0aee2039 Author: Michael Orlitzky <mjo@gentoo.org> Date: Wed Aug 24 19:08:20 2016 -0400 net-irc/dccserver: new revision with EAPI=6. This new revision updates the EAPI, and drops src_install. Everything seems to work identically to the previous revision, so the einstall from that revision (and bug 521588) was superfluous. Gentoo-Bug: 521588 Package-Manager: portage-2.2.28
