As explained in parent bug It is only valid for the oldest version... but looks like other (old) stuff need it and, then, either that should be renamed or all that old versions cleaned Thanks!
Makes sense. Done as: > 05 May 2015; Sergei Trofimovich <slyfox@gentoo.org> hdbc-2.3.1.2.ebuild: > Rename USE=sqlite3 to USE=sqlite (bug #548650 by Pacho Ramos). Thanks!
