[R] Problem with PPC packages on Intel Mac

[Michael Hopkins]

Hi all

I have recently moved to an Intel Mac and installed the latest R (2.4.0) but
I am having trouble with a number of packages.  When I try to load them I
often get the following message:

    Error: package 'pspline' was built for powerpc-apple-darwin6.8

I have tried to update all the packages I use with Package Manager but this
doesn't appear to help.

Is there some way of either updating packages so that they are all Intel
native or otherwise (presumably if there isn't an Intel native binary
available) allowing PPC-only packages to run under Rosetta emulation?

A less common error message goes like this:

    Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to
    load shared library
    '/Users/mwh/Library/R/library/mvtnorm/libs/i386/mvtnorm.so':
    dlopen(/Users/mwh/Library/R/library/mvtnorm/libs/i386/mvtnorm.so, 6):
    Library not loaded:
/Library/Frameworks/R.framework/Versions/2.3/Resources/lib/libgfortran.0.dyl
ib
    Referenced from:
/Users/mwh/Library/R/library/mvtnorm/libs/i386/mvtnorm.so
    Reason: image not found

Maybe my library paths or preferences are messed up somehow?  I'm not sure
how to check this much less rectify it.

Thanks in advance

Michael
