 There's no Mac binary because there's no rgdal on R-forge. There's
probably enough spatial packages on there that it wouldn't be a
reasonable request for them to have it..

 'weather'? I don't know why my webmaps, or brew, would need that -
did you mistype 'webmaps'?

 That would explain:

 My hypothesis is that you typed 'weather' instead of 'webmaps' :)
There is a package on r-forge called 'weather'.

 Look at the DESCRIPTION file in the SCM section:

https://r-forge.r-project.org/plugins/scmsvn/viewcvs.php/pkg/DESCRIPTION?rev=23&root=webmaps&view=markup

For webmaps you'll need:

Depends: sp, rgdal, brew, pixmap

Hope that helps!
