Warning when installing packages: Rtools is needed

I use the latest RStudio-1.2.1335.
When installing a package, either from CRAN or from a zip file, I receive a warning message saying Rtools is needed. The installation nevertheless went through.
I am not developing packages. I am just INSTALLING packages. Why would I receive the warning.

Message paste below.

 > install.packages("aod")
