>Description:
After installing the math/rpy port, there is an error trying to import the python module:

ImportError: /usr/local/lib/python2.3/site-packages/_rpymodule.so: Undefined symbol "jump_now"

>How-To-Repeat:

$python
Python 2.3.4 (#2, Aug 23 2004, 11:46:20)
[GCC 2.95.4 20020320 [FreeBSD]] on freebsd4
Type "help", "copyright", "credits" or "license" for more information.
