BuildCraft Permissions PEX?

[Piercy]

Hey,

I am setting up a tekkit server and am trying to give the buildcraft fake user permissions in pex. I am trying to make it so that quarrys can only be used on towny land and not in wilderness.

I have the following in PEX but it doesnt seem to work. Any ideas?

  BuildCraft:

    default: false

    permissions:

    - modifyworld.*

    - towny.town.*

    - -towny.wild.*

users:

  '[buildCraft]':

    group:

    - BuildCraft

I know if i OP the [buildCraft] account it's going to work but i don't want it to work everywhere.

Thanks,

Piercy
