- Ask on the bioconductor list, as this is a problem with a
  bioconductor package

  http://bioconductor.org/docs/mailList.html

- provide the output of sessionInfo() so that the specifics of your
  package version and other aspects of your system are transparent

- provide a short cut-and-paste example of the problem (the vignettes
  of each bioconductor package are built every night on 5 different
  platforms, so if this were a general problem it would have been
  noticed).

- as a shot in the dark, have you tried to update your packages to
  their most recent version, e.g., following the instructions at

  http://bioconductor.org/download

  ?

Martin
