This looks like a library problem.  Are the hyperbolic inverse 
trigonometric functions not available with your platform.  Or is their 
some header file that has to be included to get them?

These are defined in the file as long as


is not defined for your platform.

In fastumathmodule.c there is a statement there that checks for a few 
platforms and it looks like BSD is included and so 
HAVE_INVERSE_HYPERBOLIC gets defined for the rest of the compilation. 
  Doesn't FreeBSD define these?  Are you just missing a proper math 

Anybody else seen this?
