was happening with 0.11 and now with v0.11.0-492-gb204e14:

[jreback]

is there a sparc machine on vagrant so I can build this?
or somewhere I can ssh to?

[jreback]

@yarikoptic let me know if you are still having problems...thanks

[yarikoptic]

unfortunately KnownFailureTest is "no good" as is -- it is signaled as the error by nose

Ran 3500 tests in 2842.798s

FAILED (SKIP=121, errors=4)

on a good side -- all other failures I have reported for sparc before -- are "gone" now with v0.11.0-529-gcca1b7e

[jreback]

is there a way to make this pass known test failure? I guess equivalent of a skip? (or should I just skip)?

[jreback]

http://mail.scipy.org/pipermail/numpy-discussion/2010-October/053186.html

apparently known failure is a nose plugin loaded by numpy; I'll just skip these then

unless you tell me otherwise....

[yarikoptic]

yeah -- sorry for the confusion -- I have forgotten that it requires a nose plugin and not just magically works ;) indeed mandating loading of a nose plugin might be too much - skip should be enough

[jreback]

np...had never used knowntestfailure (which is a good idea!) and didn't know if its 'standard' in nose, guess not (though should be!)

[yarikoptic]

yes -- it is not standard -- grows out from numpy (used in ipython etc)

know if its 'standard' in nose, guess not (though should be!)
