I haven't ever seen that package mentioned on r-help befor, so it is  
probably a BioC package. Bioconductor which has its own mailing list.  
There are a small number of persons who are bicultural with ordinary-R  
and BioC, but they generally suggest to posters to use the BioC list.  
(I don't know if it has a Nabble interface. I'm guessing it does not.)
