[R-SIG-Mac] R CMD check fails on Snow Leopard

[cstrato]

Dear all,

Last week I have installed on my MacBook Pro Snow Leopard 10.6.3 and 
downloaded from Apple Xcode 3.2.2. Then I have installed R-2.11.0.pkg 
for Mac OS X 10.5 (Leopard) and higher.

Now I wanted to run R CMD check for my BioC package which contains C++ 
code but got the following error:

installing to /Volumes/CoreData/CRAN/xps.Rcheck/xps/libs/i386
** R
** inst
** preparing package for lazy loading
** help
*** installing help indices
** building package indices ...
** testing if installed package can be loaded
Error in dyn.load(file, DLLpath = DLLpath, ...) :
   unable to load shared library 
'/Volumes/CoreData/CRAN/xps.Rcheck/xps/libs/i386/xps.so':
   dlopen(/Volumes/CoreData/CRAN/xps.Rcheck/xps/libs/i386/xps.so, 6): no 
suitable image found.  Did find:
	/Volumes/CoreData/CRAN/xps.Rcheck/xps/libs/i386/xps.so: mach-o, but 
wrong architecture
ERROR: loading failed
* removing '/Volumes/CoreData/CRAN/xps.Rcheck/xps'

Do you have any hint what might be the reason for this error?
As far as I understand this message means that Snow Leopard is the wrong 
architecture, why?

Best regards
Christian
