The version postfix hierarchy is: alpha, beta, pre, rc, (none), p. The mythtv-plugins.eclass checks for version_at_least 0.21_pre when building the plugins list instead of version_at_least 0.21_beta. This causes media-plugins/mythmusic to build extra plugins because they don't get disabled during configure. Reproducible: Always patch attached
