after this change: http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/eclass/eutils.eclass?view=diff&r1=text&tr1=1.393&r2=text&tr2=1.392&diff_format=h , related to: http://archives.gentoo.org/gentoo-dev/msg_bf159af028ffeeb83c679d6a0eaa73e5.xml we have e.g. : * Messages for package dev-libs/mpfr-3.0.1_p4: * Old versions of installed libraries were detected on your system. * In order to avoid breaking packages that depend on these old libs, * the libraries are not being removed. You need to run revdep-rebuild * in order to remove these old dependencies. If you do not have this * helper program, simply emerge the 'gentoolkit' package. * * # revdep-rebuild --library 'libmpfr.so.1' && rm 'libmpfr.so.1' >>> Auto-cleaning packages... Missing the complete path of the library
I think this is mpfr-specific. And there is the mpfr hack right above that line, so... # temp hack for #348634 #357225 [[ ${PN} == "mpfr" ]] && lib=${lib##*/} ewarn " # revdep-rebuild --library '${lib}' && rm '${lib}'"
