Rpy2 And Mac Os X 10.6

Question

[Science_Robot]

I know there's already a question for 10.5 but I have 10.6 and a different error.

I have R 2.11.1 and Python 2.7 (Same error w/ 2.6):

R was installed with homebrew.

Any ideas?

As usual, I asked a question on Biostar and then came back 5 minutes later to answer it.

I commented out the lines producing the error in setup.py: 251-253

    #if not ok:
    #    raise ValueError('Invalid substring\n' + substring 
    #                     + '\nin string\n' + string)

Installation works, I ran the tests in rpy/robjects/tests and everything came out OK.

import rpy2 works as well.

But I have the feeling that something somewhere is deeply wrong.

[Laurent Gautier]

import rpy? Is this about rpy or rpy2? If rpy2, what is the version you are trying out?

Otherwise, you are commenting out a section that stops the install when something unexpected is happening. This seems to indicate that the homebrew R is built/installed not quite the way the script anticipates it.
