[BioC] multtest -- unable to load shared library '/Library/Frameworks/R.framework/Resources/library/multtest/libs/multtest.so'

[Paul Shannon]

Building from source (http://bioconductor.org/packages/1.8/bioc/src/ 
contrib/multtest_1.10.0.tar.gz)
on Mac OS X, I see that the shared library ends up in

    /Library/Frameworks/R.framework/Versions/2.3/Resources/library/ 
multtest/libs/ppc

but .First.lib seems to be looking only in

    /Library/Frameworks/R.framework/Versions/2.3/Resources/library/ 
multtest/libs

and thus reports 'unable to load shared library'.

I created a symlink (from libs/multtest.so to libs/ppc/multtest.so)  
and now
multtest loads fine.

I will not be surprised at all :} if I am missing something obvious  
here.
Am I merely papering over my ignorance by making that symlink?

Thanks -
