sage built on a FreeBSD 64 bit machine fails the test
{{{
sage -t -force_lib "devel/sage/sage/combinat/partition.py"
}}}
After some googling, I get the impression that long double is at best
flaky on FreeBSD.
I am going to suggest the following patch, although it is perhaps not
necessary for the i386 version of FreeBSD.

// On sparc solaris long double is bad/broken/different, etc. E.g.,
// LDBL_MANT_DIG is 113 rather than 106, which causes all kinds of
trouble.
// So we only use double_precision.
