I'm trying to install  a package on OS X (Snow Leopard) using the following
command, but instead of respecting the arch directive it install i386. How
can this be resolved?


R --arch=x86_64  CMD INSTALL ....
* installing to library
‘/Library/Frameworks/R.framework/Versions/2.15/Resources/library’
* installing *source* package ‘Rhipe’ ...
** libs
*** arch - i386
g++ -arch i386 -I/Library/Frameworks/R.framework/Resources/include -I.....



My system (from cmd: R --arch=x86_64 )
R version 2.15.2 (2012-10-26) -- "Trick or Treat"
