I tried to install IRanges package using biocLite() on my linux box, I got the following error:

…

Error in setGeneric(f, where = where) :

  'anyNA' is a primitive function;  methods can be defined, but the generic function is implicit, and cannot be changed.

Error : unable to load R code in package 'IRanges'

…

Not sure what happened. Below is my session info. Any help will be appreciated!
