I just tried installing Anaconda on Linux 64 bit. Everything seems to have worked well, but when I tried to start IPython from a terminal, I get the following error:
$ ipython
Traceback (most recent call last):
File "/home/josh/installs/conda/1.7.0/bin/ipython", line 4, in <module>

I get the same error if I try to update conda:
$ conda update conda
Traceback (most recent call last):

It is also strange because it looks like it installed Python 2.7.4 and not Python 2.7.5. I literally downloaded it just now (October 1st).
$ python
Python 2.7.4 (default, Apr 21 2013, 18:37:10)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-50)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
and I have the following on my .bashrc:
PATH=/home/josh/installs/conda/1.7.0/bin:$PATH
which seems to be doing its job:
$ which python
/home/josh/installs/conda/1.7.0/bin/python
I installed the version available here. Below is the full installation log:

Do you wish the installer to prepend the Anaconda install location
to PATH in your /home/josh/.bashrc ? [yes|no]
[no] >>> yes
Prepending PATH=/home/josh/installs/conda/1.7.0/bin to PATH in /home/josh/.bashrc
A backup will be made to: /home/josh/.bashrc-anaconda.bak
For this change to become active, you have to open a new terminal.
Thank you for installing Anaconda!
