The "Assigning files to ebuilds" stage which generates the list of ebuilds from the list of files which are missing libraries has a bug. Specifically, simply "fgrep"ing CONTENTS files which contain the name of a broken file: find /var/db/pkg -name CONTENTS | xargs fgrep -l -f $LLIST.3_rebuild | sed 's:/var/db/pkg/\(.*\)/CONTENTS:\1:' > $LLIST.4_ebuilds finds not only exact matches but also substring matches. A concrete example: my /usr/bin/dia (from app-office/dia) is broken by a recent expat upgrade, so ~/.revdep-rebuild.3_rebuild contains a line: obj /usr/bin/dia The fgrep command not only matches /var/db/pkg/app-office/dia-0.95.1/CONTENTS, which has: obj /usr/bin/dia dfc5d8300ad9138dc4fb39eb3004236a 1171745643 But also matches /var/db/pkg/dev-util/dialog-1.1.20070704/CONTENTS, as that has: obj /usr/bin/dialog 34122ee1f5280476e0383f5ac83efcb0 1192820107 Reproducible: Always Steps to Reproduce: Potential fix: make a temporary copy of .3_rebuild with a space at the end of each line. Use that file for fgrep -f.
