[R-SIG-Mac] Installing package from source

[Simon Urbanek]

There is a lot of missing pieces, but I bet that your package links unversioned libatlas-MacPro.dylib instead of libRblas.dylib and you don't have the appropriate symlinks in x86_64. (Just for the record: this is "your mileage may vary" setup and is NOT what you get when you install R). There are several solutions:

a) switch back to R BLAS when building your package (this is the default in "normal" R)

b) make a symlink from to all sub-arch directories (i386, x86_64 possibly ppc) to libatlas-MacPro.dylib. This is a just a hack - your binaries won't work on anyone else's machines.

c) add versioned path to your libatlas-MacPro.dylib using install_name_tool -id, preferably pointing to libRblas and NOT the MacPro variant, i.e. for R 2.13.x:
install_name_tool -id /Library/Frameworks/R.framework/Versions/2.13/Resources/lib/libRblas.dylib libatlas-MacPro.dylib

Cheers,
Simon
