problems building rpy in linking, appreciate advice?

[John Owens]

Greetings, I'm trying to write a port for rpy, a python
set of bindings for R. I'm attaching the build log below.
Basically the problem is that it's trying to link to a
dynamic library "libRblas.dylib" that is clearly in the 
right place (/opt/local/lib/R/lib/libRblas.dylib) and whose
directory is explicitly specified with -L. (LD_LIBRARY_PATH
didn't help either.)

Suggestions?

This is my first port of this type - it seemed to figure out
all sorts of stuff automatically (like to run setup.py). I
didn't really have much in the portfile (I'll attach it 
at the bottom).
