Hi Folks,

I'm trying to load devtools in R 3.0.1 in order to run the dev version
of lme4.  I've updated devtools, and just installed Rtools30.exe. 
However, I get the following warning (in R-Studio, RGui, and R.exe, both
x64 and i386):

There's a bit of chicken-and-egg problem here, but devtools
has recently been updated to deal with this problem.

  Until a new version makes it onto CRAN, you might have to 
clone/download the repository and install the package from there.
(Let me know off-list if you want me to pack up the package and
send it to you ...)
