With the following packages installed: app-portage/gentoolkit-0.3.0.5 sys-apps/grep-2.11 In the euse file, line 1144: if [[ -n $(echo "${line}" | egrep -re "^[^#]*${PACKAGE} ") ]]; then egrep -re takes a long time to finish because it recursively checks all files in cwd. This is because the behaviour of grep changed as follows in the 2.11 release: [http://savannah.gnu.org/forum/forum.php?forum_id=7132]: NEWS * Noteworthy changes in release 2.11 (2012-03-02) [stable] ** New features If no file operand is given, and a command-line -r or equivalent option is given, grep now searches the working directory. Formerly grep ignored the -r and searched standard input nonrecursively. An -r found in GREP_OPTIONS does not have this new effect. I think the -r is not needed here. I removed it and everything seems to work fine.
Thanks! Fixed in the following commit: http://git.overlays.gentoo.org/gitweb/?p=proj/gentoolkit.git;a=commit;h=34f3d9824db09afe71e5254e2f75f9379b7c2b63
