Supressing PyChecker warnings

[Jp Calderone]

  When using PyChecker on a project which uses bsddb, dozens of messages
like the following are reported:

warning: couldn't find real module for class
         bsddb._db.DBAccessError (module name: bsddb._db)

  I've looked through the PyChecker usage information, documentation, and
browsed some of the source, but I can't find any options for supressing
this.

  Is it possible?  If so, how?

  Thanks in advance,

  Jp
