Just out of curiosity.

Humor me for a bit and let's assume that in many cases, the machines  
that people are building numpy/scipy on will most likely also have  
some install of R. Perhaps it's a compute server in your lab, or your  
own machine (for which pre-built versions of R most likely exist  

Is it possible to conjure up some special flag people can use during a  
numpy/scipy build/install so that they are able to link against the  
packaged libraries in the canonical install of R for their platform,  
or is that a totally bone-headed idea?
