I'm having the following problems with Net::HTTP on ruby 1.6.4 (and 1.6.5) =
on
FreeBSD 4.4-RC.. I suspect it to be a bug specific ruby on the platform act=
ually
since it works on my OS X box fine.

Basically, I get this output when running a monitor script I wrote (code wi=
ll
follow)

code is at the bottom of this message.  Is there a reason why this would wo=
rk
on one platform and not another?  One thing to note is that I did install r=
uby
from the ports collection on the BSD box.  If there is a workaround I can d=
o in
the mean time, let me know :-)

Thanks in advance,
