[R-SIG-Mac] Unable to load local library via GUI

[Simon Urbanek]

Noel,

the package uses BLAS and your R is setup to build against vecLib BLAS which has bad ID so anything linked against it will have trouble finding libRblas. The simple fix is to switch to R BLAS instead of vecLib BLAS (see R for Mac FAQ 12.5). Alternatively update to R 2.13.2, the issue has been fixed in the CRAN binary distribution of R 2.13.2.

Cheers,
Simon
