Please try out the attached patch to the recent new tests added by Robert T.
Short (cc'ed for comment as well).  I pulled out my copy of Abramowitz &
Stegun to double check the failing tests and found some missing negative
signs.  Also one of the calls to besselk was missing the last argument.

I also think the tolerance on the modified Bessel functions is too tight,
which is why it was failing for me, so I doubled it, see if that works for
you, but may still be too small.  For example, A&S Table 9.8 has
besselk(2,20,1) only to 8 significant digits and a tolerance of 1e-8 just
doesn't make sense.
