Following some steps from here that may have been updated since you were installing:
[afni.nimh.nih.gov]

... can you run this:

cd 
curl -O [afni.nimh.nih.gov]
tcsh @update.afni.binaries -defaults -package macosx_10.7_local

which will take care of a lot of the library errors you are seeing.

Then you should be able to run

sudo rPkgsInstall -pkgs ALL

more easily to install the R packages.

Let us know how that goes.
