add a bool option named "use_rpaths".  default it however you like (True or 
False).  the point is i get to build it with "False".

then add a non-bool option named "rpath".  if "use_rpaths" is enabled, then 
use this value as the RPATH.  default it however you like (like using the 
crazy ldconfig hacks).
