# The gem for this package doesn't seem to play well with portage.  It
# runs a GNUish configure script, with argument passed directly from
# the gem install command, but gem install doesn't use the same style
# of arguments.  Thus, unless you're smart enough to come up with a
# fix, please leave this as a source package install.
