Allow parallel builds to work.

If the .so doesn't get built before we invoke the PL scripts, they may find an older version elsewhere in the path and fail with a "does not match bootstrap parameter" error. Thus, make a dependency so we don't run those PL scripts until we have the new .so ready.

Fixes #62
