 Where does a Maccer get the 'brew' command from? Reading these docs:

http://mxcl.github.io/homebrew/

seems to imply you first need Ruby. Is that installed on every Mac?


does that brew command require an rgdal 'formula' somewhere? I cant
find one here:

https://github.com/mxcl/homebrew/blob/master/Library/Formula

or is it a case of installing R from homebrew and then 'gdal' for the
libraries and then the rgdal package via install.packages from source?

1. install Ruby
2. install homebrew
3. start a Terminal
3.1  brew install r
3.2  brew install gdal
4. run R
4.1 install.packages("rgdal",type="source")

?
