Comment(by drkirkby):
I decided to test the
http://cage.ugent.be/~jdemeyer/sage/sage-4.6.prealpha0.tar on my
!OpenSolaris machine. Sage has never passed all the doc tests on
!OpenSolaris, so I did not expect it to. I'll list the failures and what I
think they are due to. There's one unexecpted failure.
A better test would be on 't2', but that takes forever to build Sage. This
is an order of magnitude quicker.
{{{
The following tests failed:

1) {{{devel/sage/sage/lfunctions/sympow.py}}} SYMPOW is the worst code
I've ever seen in Sage and is broken on Solaris x86 (#9703), Cygwin
(#9166) and reportedly !ArchLinux too. The examples at
http://www.sagemath.org/doc/reference/sage/lfunctions/sympow.html do not
work if you try them on sage.math, so I we can ignore this failure. The
code in SYMPOW is so bad, I can't really be bothered to try to fix it.
2) {{{devel/sage/sage/rings/polynomial/polynomial_quotient_ring.py}}}
'''An unexpected failure.'''
3) {{{devel/sage/sage/modular/abvar/abvar.py}}} Caused by SYMPOW. So we
can ignore that.
4) {{{devel/sage/sage/modular/hecke/submodule.py}}} Again, caused by
SYMPOW, so we can ignore that.
5) {{{devel/sage/sage/schemes/elliptic_curves/ell_rational_field.py}}}
Again, caused by SYMPOW, so we can ignore that.
6) {{{devel/sage/sage/stats/hmm/chmm.pyx}}} This is numerical noise,
#9735, which will hopefully be merged soon.
7) {{{ devel/sage/sage/symbolic/expression.pyx}}} Again numerical noise
(#9689 & #9693).
So the unexpected failure I see was this one:

Could that be due to Pari? If not, and you know where I should look for
the cause, let me know.
