For what it's worth, I noted the same bug a couple weeks ago.  In case
it didn't go through, I said:

I have installed rpy2 on this machine in the past and had no problems,
but now I am unable to get rpy2 properly installed either using pip or
source.  I'm running OSX 10.9.5 (Mavericks), and R version 3.1.1
(2014-07-10) -- "Sock it to Me" (Platform: x86_64-apple-darwin13.1.0
(64-bit)).

Both source and pip show similar errors. For example, when I try

pip install https://bitbucket.org/lgautier/rpy2/get/version_2.5.x.tar.gz

I get the following traceback:

-------------------------------------------------

Traceback (most recent call last):
  File "<string>", line 17, in <module>
  File 
"/var/folders/7h/kxq84vrx6cq4mh8ycssjhzc4y2bpx0/T/pip-M_AK2m-build/setup.py",
line 275, in <module>
    ri_ext = getRinterface_ext()
  File 
"/var/folders/7h/kxq84vrx6cq4mh8ycssjhzc4y2bpx0/T/pip-M_AK2m-build/setup.py",
line 189, in getRinterface_ext
    ldf = shlex.split(' '.join(rexec.cmd_config('--ldflags')))
  File 
"/var/folders/7h/kxq84vrx6cq4mh8ycssjhzc4y2bpx0/T/pip-M_AK2m-build/setup.py",
line 135, in cmd_config
    output = output.strip()
AttributeError: 'list' object has no attribute 'strip'
-------------------------------------------------

(I used https://bitbucket.org/lgautier/rpy2/get/version_2.5.x.tar.gz
because I was seeing a separate error before this, and while trying to
find a solution to that one I saw the suggestion to use
https://bitbucket.org/lgautier/rpy2/get/version_2.5.x.tar.gz.  That
eliminated the previous error but brought in the "strip" error.)

On trying to install from source (rpy2 2.5.1)

 I get a similar error:
-------------------------------------------------

~/Downloads/rpy2-2.5.1 > python setup.py build install
R version 3.1.1 (2014-07-10) -- "Sock it to Me"
/Library/Frameworks/R.framework/Resources/bin/R CMD config --ldflags
Traceback (most recent call last):
  File "setup.py", line 278, in <module>
    ri_ext = getRinterface_ext()
  File "setup.py", line 192, in getRinterface_ext
    ldf = shlex.split(' '.join(rexec.cmd_config('--ldflags')))
  File "setup.py", line 135, in cmd_config
    output = output.strip()
AttributeError: 'list' object has no attribute 'strip'

-------------------------------------------------

I made a guess that the offending line should be output[0].strip() but
then I got the following error:

-------------------------------------------------

Traceback (most recent call last):
  File "setup.py", line 280, in <module>
    ri_ext = getRinterface_ext()
  File "setup.py", line 206, in getRinterface_ext
    include_dirs.extend(args.I)
TypeError: 'NoneType' object is not iterable

-------------------------------------------------

Suggestions welcome.
