After upgrading sys-libs/readline to 6.0 from 5.2_p13, app-office/abiword-plugins-2.6.8 was one of many applications that were part of the preserved-rebuild set (sys-apps/portage-2.2_rc30) that needed to be re-emerged. However, abiword-plugins failed to rebuild because of a missing /usr/lib64/libpcre.la (i.e. nothing to do with readline as such, AFAIK). Reproducible: Always Build log follows as a an attachment.

Probably invalid (related to recent libpcre ebuild changes). Try revdep-rebuild first (or today's new package/script lafilefixer).
yes, this is caused by bug 266016. Following Rafał's suggestion should fix it. Please reopen if not. *** This bug has been marked as a duplicate of bug 266016 ***
(In reply to comment #3) Thanks for the reply. revdep-rebuild was the answer: abiword-plugins and a number of other libpcre-dependent packages were successfully rebuilt. I really should have tried revdep-rebuild before filing a bug and not relied only on the preserved-rebuild set feature of recent portage, which doesn't seem to handle deep dependencies well/at all? (or perhaps the situation in #266016 is unusual). Anyway, thanks again.
