R CMD build <mypkg> does not compile anything except for creating the 
vignettes. Is this the case?
If so: During the pre-release cycle of R-2.12.0 we have not got any 
report telling us this is a desirable feature.

For now, you can use an only 32-bit installation of R in order to build. 
Passing down a flag such as --no-multiarch will be considered.

Yes, http://cran.r-project.org/bin/windows/contrib/2.12/@ReadMe tells us:

     Cairo, RBrownie, RSvgDevice, RSVGTipsDevice, SNPassoc, coxphf, eco,
     gcmrec, magnets, proj4, ripa, sampfling, survrec, yaml
are only available for 32-bit installations.
