[R-SIG-Mac] Writing R package that calls Fortran on Mac os X El Capitan Error

[Kodalore Vijayan, Vineetha W]

My namespace contains:

useDynLib(randomepi)
useDynLib(Nepidemic, .registration = TRUE)
exportPattern("^[[:alpha:]]+")
export(randomepi)
import(graphics,grDevices,stats, utils)

Any thoughts?

Thanks,
Vineetha
