Thanks. I'm working with Frederic on this.
On the first machine, both the 32 and 64 bit versions are Rcpp are
installed (I can library(Rcpp) from both R --arch i386 and R --arch
x86_64), and the installed Rcpp has these files present:

pwd
/Library/Frameworks/R.framework/Versions/Current/Resources/library/Rcpp
PETTY:Rcpp biocbuild$ ls -lR libs
total 0
drwxr-xr-x  3 biocbuild  admin  102 Dec  3 11:40 i386
drwxr-xr-x  3 biocbuild  admin  102 Dec  3 11:40 x86_64

-rwxr-xr-x  1 biocbuild  admin  619064 Dec  3 11:40 Rcpp.so

-rwxr-xr-x  1 biocbuild  admin  651920 Dec  3 11:40 Rcpp.so
PETTY:Rcpp biocbuild$ ls -lR lib

drwxr-xr-x  4 biocbuild  admin  136 Dec  3 11:40 i386

lib/i386:

-rw-r--r--  1 biocbuild  admin  5177484 Dec  3 11:40 libRcpp.a
-rwxr-xr-x  1 biocbuild  admin   619064 Dec  3 11:40 libRcpp.dylib

After building rTANDEM against this Rcpp, I then get the same error
Frederic reports in this thread when trying to library(rTANDEM) on the
x86_64 architecture. Here it is again with sessionInfo():

I'm not sure if Frederic wants the package source to be posted at this
point. I'll let him answer that.

Thanks,
Dan
