[BioC] "GOHyperGResult" is not a defined class

[Paul Shannon]

Hi all,

I have encountered a puzzling problem with the ever-reliable  
hyperGTest function.  It
runs the usual amount of time (30 or more seconds) and then fails  
with the message
that 'GOHyperGResult' is not defined.    Here is the whole of my  
session, with sessionInfo
attached.

Any ideas?  Thanks!
