After upgrading to BioC 3.4 it turns out I cannot load the library multtest anymore. Uninstalling followed by reinstalling, even from source, does not solve it. Is this something specific to my system, or a more general error?

Thanks, Guido

Sorry, problem has been solved; question can be ignored.... Sorry for this noise.

Although biocValid() did not return any problems, as a last resort I manually re-installed the dependencies of multtest, i.e. survival and MASS. After starting a new R-session, multtest now loads without any errors.... ???
