Hi
I have modified the path to
dyn.load(paste(Sys.getenv("R_LIBS_USER"),"/fortran/src/fortran.so",sep=""))
and the package could installed, loaded and the lines with dyn.load worked.
It does not look like a pretty solution but works on my linux (I am not sure
if it works on my mac or windows).
I am not sure if this is what you meant but as I have no clue what
.First.lib does or NAMESPACES means this is the best I come up with.
Please correct me if I am wrong.
Many thanks
Ed
