Hi all,

Using the following command to compile a package for 64bit  
architecture, I get a strange warning

dutangc at dtgMacBook(~/rmetrics/pkg)R CMD INSTALL --arch=x86_64  
Warning: unknown option '--arch=x86_64'
* Installing to library '/Library/Frameworks/R.framework/Resources/

Everything is compiled correctly. In R64 GUI, the package is loaded  

How could I get rid of this warning?

Furthermore, if I launch R GUI, the package could not better loaded  
any more on 32 bit architecture... I got
Error: package 'randtoolbox' is not installed for 'arch=i386'

How could I use both architecture at the same time (from different  
GUIs). I need to compare outputs of the halton function between the  
two architectures.

Thanks in advance
