It does not sound like the same problem unless you only mean that it  
also involves difficulties with installing a package.

R does not check for the existence of other R package dependencies (or  
for the existence of external libraries)  at the time of installing a  
binary package. If I understand you correctly that is what you did. It  
would not have anything to do with the Mac GUI. If you compile from  
source there is an effort to load the package after compilation.  
Missing dependencies would necessarily show up at that stage.  The GUI  
package installer does have a checkbox to "Install Dependencies" and I  
assume you would have gotten an informative error message had you used  
that checkbox.

I do not know if the `install.packages` command would allow you to  
specify multiple repositories in which to search if you had set  
dependencies=TRUE in the call. The help page says 'repos' needs to be  
a character vector, so maybe it would succeed.  I would not have  
expected the GUI installer to be able to do that in its current  
incarnation.
