[R] Help with "error: no acceptable C compiler found in $PATH"

[R. Michael Weylandt]

Yes, you probably need some sort of C compiler, but why can't you just
download the appropriate binary directly? I just did on OS X 10.5.8
(admittedly for R 2.13.2, not 2.14) with no problems. The output of

sessionInfo()
install.packages("RCurl")

if you don't mind please.

Thanks,

Michael
