ports/151704: port update: devel/boost-libs to 1.44.0

[Armin Pirkovitsch]

I've already made a patch for 1.44 - however since 1.45 is planned to be 
released on 01.11.2010 I plan to to submit a patch for that version 
instead - I see no reason to push that kind of library in last minute - 
but that's just imho.
(If the maintainer of boost wants that patch however I'm willing to send it)
