gnome2-fifth-toe uses 'boot-admin' to check for gnomesystemtools being
installed, but gnomesystemtools doesn't apparently install it
(anymore?). I might have a problem with some other tool, but it
definitely doesn't install. Try recursively removing
gnomesystemtools, then install it, then try to install
gnome2-fifth-toe - it willl try to install gnomesystemtools again.
