I tested sage-5.9.beta2 and got errors like this:
{{{
"sage -t devel/sage/sage/plot/plot.py"
**********************************************************************
File "devel/sage/sage/plot/plot.py", line 942, in sage.plot.plot.plot
Failed example:
plot(gamma, (-3, 4), detect_poles = True).show(ymin = -5, ymax = 5)
Expected nothing
Got:
<BLANKLINE>
tgammal domain error
**********************************************************************
File "devel/sage/sage/plot/plot.py", line 946, in sage.plot.plot.plot
Failed example:
plot(gamma, (-3, 4), detect_poles = 'show').show(ymin = -5, ymax = 5)
Expected nothing
Got:
<BLANKLINE>
tgammal domain error
}}}
This is because FreeBSD uses the cephes math libraries. These output
error messages to stdout when they shouldn't.
The following patch removes all the print statements from files called
mtherror.c in cephes.
