It is so.

Yep.

So does not being able to run alot of system utils if you're on a
386/486SX class machine, which are still in common use by many folks
using FreeBSD.

And, it's really easy to re-compile the math libraries. :)

I suspect there are more users who are concerned about having everything
work right all the time out of the box than who are concerned about
having it go as fast as possible on the high-end hardware.

I *always* recompile the math libraries on my boxes, and on high-end
hardware that has built in FPU is a 10 minute process (or 30 seconds
on a high-end PPro box. :)
