this works with latest master so not sure what the problem is (I matched your installed versions).

Here are some windows builds of a test version of 0.15.2 (0.15.1 is officially the current release)

https://github.com/pydata/pandas/releases

[jlec]

I see the same error with current HEAD.

[jreback]

the error report you have doesn't match the show versions

first is in py3.3 and 2nd says py2.7

which is it??

[jlec]

it is with every python version

for dateutil 2.3 might be related to #9021

@jlec you are showing several different versions of dateutil here, so very confusing. I think that this may be broken on your linux version. You can provide a debug output (e.g. run nosetests with --pdb --pdb-failure and show the variables that are being compared (you have to go up a couple of levels).

[jreback]

ok, this is ONLY on >= 2.3. The attached PR #9036 now shows the issues (was being suppressed somehow on windows).

I think the API changed in 2.3

[jlec]

Do you need anything from me, or is the issue clear?
