Your code calls the C entry point errmsg, and that is not in the R binary.  
So find out what library it is in and link against it.  NB: it does not
show up on our Solaris 8 system at a quick look.

I think the error message is pretty explicit, so maybe you need to take 
local advice about your C code.
