Upgrading xfce today revealed this dependency issue - since xfce-utils does not depend on xfce-mcs-manager portage decided to update it first, causing this configure error: checking for xfce-mcs-manager >= 4.3.99.2... found, but 4.3.90.2 *** The required package xfce-mcs-manager was found on your system, *** but the installed version (4.3.90.2) is too old. *** Please upgrade xfce-mcs-manager to atleast version 4.3.99.2, or adjust *** the PKG_CONFIG_PATH environment variable if you installed *** the new version of the package in a nonstandard prefix so *** pkg-config is able to find it. The (very simple) attached patch corrects the issue.
