It should be mentioned that if not using a "all-in-one" version of buildcraft, the Logistics pipes depends on BC-Transport, BC-Silicon and most likely BC-Core. I found this out the hard way from crash log.

And don't forget BC Robotics too - at least temporary while you get rid on this dependency.

I don't get server crash while not having robotics. Are they required for LP itself? I'm new to the mod and haven't gotten to learn the details yet.

Yep, but IIRC not at startup. There was an issue regarding to runtime dependency to Robotics.

This will not be relevant in 0.10 anymore, because BC independence. I guess people have lived with it for 0.9 and therefor a wontfix now.
