title: package doMC NOT available for R version 3.0.0 warning in install.packages
body: <p>For some packages like doMC &amp; doSMP, i get the warning &amp; inability to library(doMC).
  As shown below, i have no problem with subselect thus no file/directory permission issue.
  Also tried repo=<a href="http://cran.us.r-project.org" rel="noreferrer">http://cran.us.r-project.org</a> &amp; others, no luck.
  please advise.</p>
  
  <p>ps: for the unexpected Japanese characters, i have no clue; i assume that is a separable issue; no response yet from support.rstudio.org/help/discussions/problems/6009-japanese-characters-show-unexpectedly</p>
