[IPython-dev] Trouble installing latest IPython 2.0 on Mac

In case it matters, I¹m doing this in a conda environment. I¹ve run conda
install pip and conda install readline (etc.) ahead of time.
I try:
$ pip install --no-deps -e ".[notebook]²
and it ends with

    Installed /Users/alessandro.gagliardi/Devel/ipython
Successfully installed ipython
Cleaning upŠ

But when I try 
$ ipython
It gives me

Traceback (most recent call last):

(FWIW, if I run strait up python and import readline, it works fine.)

Since that didn¹t work, I tried using setup.py as you recommended, but I
may have done it wrong. First:

$ python setup.py symlink

Etc. etc. etc.


So it looks like setup.py symlink is finding readline but then when I try
to install it gives me the same error.

From: MinRK <benjaminrk at gmail.com>

This is a problem in both Anaconda and readline because of Anaconda's
unfortunate choice of 10.5 as the target SDK, which then readline doesn't
properly handle because the system is not actually 10.5, and it fails to
build. I actually have fixes <https://github.com/conda/conda-build/pull/42>
out <https://github.com/ludwigschwardt/python-readline/pull/31> to both,
respectively, which will hopefully resolve before we release IPython 2.0.
If they don't, I'll revert the annoying checking we have for readline on OS
X so that it will install on Anaconda.

In the meantime, you can install IPython with

    pip install --no-deps

which will ignore the dependencies, and/or use the `setup.py symlink`,
which is nicer than `pip install -e` or `setup.py develop`, and doesn't use
setuptools, so it will not install dependencies.

Yeah, I had already done that. Bear in mind, I do have a "free"
account ...

Here's a tip, in case anybody's interested. My support "ticket"
didn't get answered for several days. Then, today, I noticed there
was a support "chat" available. That was picked up immediately
and the person was able to answer me. (I did close the ticket :-)
