One of your mods is providing an outdated version of the BuildCraft API - you can tell by its JAR file containing a buildcraft/api/mj directory.

Either get rid of its outdated copy of the BuildCraft API by editing the JAR - note that redistributing such a modified JAR might have licensing problems - or, preferably, report to the mod author bundling this outdated version of the API.
