The attached diffs generated by PARI look weird since PARI breaks the
output into fixed width lines (and compares these) - even '''within
numbers''' that would fit on a single line.
I've reformatted both the expected and the actual output s.t. the
differences are more readable; now more obviously this is just
'''numerical noise''':

}}}
At least in Sage 4.6.alpha0 the slight deviation doesn't affect
{{{ptestlong}}}, i.e. all tests passed regardless of PARI's self-tuning
being enabled or not.
Nevertheless it's odd PARI's test suite fails with tuning enabled, since
* Sage will reject to install the package when {{{SAGE_CHECK=yes}}},
* analyzing the failures is quite tedious, and
* disabling the self-tests is potentially dangerous.
----
On the same machine running Fedora 13 x86 (gcc 4.4.4) PARI's self-tuning
hangs when tuning {{{REMIIMUL_LIMIT}}}, i.e. the output stops, but
{{{tune}}} doesn't terminate. This should be reported upstream as well.
