Using a testing gentoo system, all ~x86 packages, verve fails to install. I have submitted how I worked around the problem, which is at the end of this bug.
1. Use ~x86
2. emerge verve
Results in a configuration error where it is unable to find libexpat.so.0. The error looks like this.
dbus-binding-tool: error while loading shared libraries: libexpat.so.0: cannot open shared object file: No such file or directory
make: *** [verve-dbus-service-infos.h] Error 127
make: Leaving directory `/var/tmp/portage/xfce-extra/verve-0.3.5/work/verve-plugin-0.3.5/panel-plugin'
make: *** [all-recursive] Error 1
make: Leaving directory `/var/tmp/portage/xfce-extra/verve-0.3.5/work/verve-plugin-0.3.5'
make: *** [all] Error 2
Fix: create a symlink to libexpat.so.0 as the system already has libexpat.so.
1. ln -s libexpat.so libexpat.so.0
2. emerge -vat verve
