I have checked some other SO answers and googled somewhat extensively and cannot seem to find someone who has asked/answered this:
I am running Ubuntu 12.04. I have python2.7 and python3.2 installed. (I ran sudo apt-get install python-numpy, python3-numpy, and similar with scipy). I ran sudo apt-get install python-pandas. It works perfectly fine with python2.7. It does not import in python3.2 I then modified my $PYTHONPATH to have the directory where pandas was installed, full aware that this might create an issue:
/usr/lib/pymodules/python2.7
Now when I try to import, I get
>>> import pandas
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/pymodules/python2.7/pandas/__init__.py", line 10, in <module>
import pandas.lib as lib
ImportError: /usr/lib/pymodules/python2.7/pandas/lib.so: undefined symbol: _Py_ZeroStruct
So I've obviously missed something here. As a note, since I've just been doing all these python installations myself, and am still learning, my $PYTHONPATH may need updating; right now the only thing in it is the directory mentioned above. Are there other directories I should have in there, standardly?
(If you need any more information about my system, etc., please just comment.)

Update
As mentioned below, pandas is now available for python 3.3, 3.4 and 3.5 source
For system wide install use:
sudo apt-get install python3-pandas
Original:
If this information http://packages.ubuntu.com/precise/python/ is correct there is no pandas package for Python 3. You can install current pandas using virtualenv:
apt-get install python-virtualenv virtualenvwrapper
mkvirtualenv -p python3 pandas_env
pip install pandas
Generally it is a good idea to create separate virtual environments when working with Python and to avoid manual messing with system wide packages.
