Trouble with Biostrings

Question

[mcc]

I am having trouble loading Biostrings. I get this error. I believe I have the correct versions as far as Ubuntu 14.04 repositories are concerned. I have loaded XVector and still get this. Where can I find out which versions work with what versions of Biostrings?

> require(Biostrings)
Loading required package: Biostrings
Loading required package: XVector
Error : .onLoad failed in loadNamespace() for 'XVector', details:
  call: get(name, envir = asNamespace(pkg), inherits = FALSE)
  error: object 'setDefaultSlotValue' not found
Failed with error:  'package 'XVector' could not be loaded'

Does biocLite(c('XVector','Biostrings')) help?
