py-rpy2 @2.4.2 python -m 'rpy2.tests' fails

[Liontooth (David Liontooth)]

On a fresh build of R and py-rpy2:

$ python -m 'rpy2.tests'
rpy2 version: 2.4.2
- built against R version: 3-1.0--65387
- running linked to R version: R version 3.1.0 (2014-04-10)
E

Or also

$ python

>>> import rpy2

>>> suite = rpy2.tests.suite()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'suite'

Are these different versions of R or just labeled differently?

Cheers, Dave

1. Ipython is an optional dependency for rpy2 tests.
2. For some reasons manual tests from official documentation doesn't work (​http://stackoverflow.com/questions/24662036/bug-with-rpy2-test-suite). But you can run tests via separate commands like:

python -m 'rpy2.robjects.tests.__init__'.
