>Description:
The update of math/R to 3.0.2 broke compatibility with the existing math/rpy2 port. This is caused by a change to the R API, discussed here:

https://bitbucket.org/lgautier/rpy2/issue/150/rpy2-crashes-upon-import-with-r-302

A fix has been implemented in rpy2 as of version 2.3.8. Recommend updating the existing math/rpy2 port to version 2.3.8. This can be trivially done by just bumping the version number in the Makefile and updating the distinfo.
>How-To-Repeat:
Install math/rpy2. It draws python2.7 and R 3.0.2 as dependencies.
Open a python prompt and issue the command:

from rpy2 import robjects as r

it will respond with the error:
Error: 'rho' must be an environment not NULL: detected in C-level eval
Segmentation fault (core dumped)

>Fix:
Update math/rpy2 to version 2.3.8
