[BioC] Dunnett\'s test for greater than 1000 groups

Dear R/Bioconductor users
I'm trying to find a package to perform a Dunnett's test comparing the response from a large number of groups to a single control group. I have tried the "multcomp" package, but when I try to print the summary, I receive the following message:
"Error in mvt(lower = carg$lower, upper = carg$upper, df = df, corr = carg$corr, :
only dimensions 1 <= n <= 1000 allowed"
I have also looked into the simTest package, but some comments on the R mailing lists says that simTest only constructs the Dunnett's contrasts but does not perform a Dunnett's test.
Are there any packages available to do this?
Thank you!
Jason
