It's now on the main site at CRAN, and should propagate to the mirrors
reasonably quickly. I'm hoping that tomorrow's R-devel build will use
it, but there may be some last minute problems.
I think R-devel will have some trouble finding the compilers if they
aren't in the default install locations in c:\Rtools. This should be
fixed in a few days, probably by requiring an environment variable to
specify where Rtools is installed.
In the meantime, if you get "gcc not found" errors, you can manually
edit the etc/*/Makeconf file in the R-devel binary install, and set
BINPREF to <Rtools>/gcc492_32/bin/ for *=i386, and set BINPREF64 to
<Rtools>/gcc492_64/bin/ for *=x64.
