Yep, if you like, you can check out the branch 
(haiku/branches/team/build/build_system_redesign). It is supposed to be 
able to build a Haiku image from the sources under Linux. There's a script 
included that builds the cross compilation tools from the sources 
(build/scripts/build_cross_tools) and you have to specify them for the 
configure script (--cross-tools-prefix, see --help).

The build system won't work on *BSDs yet, mainly because they haven't been 
added as target yet. If you want to give it a try you can grep the 
configure script and the build system files in build/jam/* for "linux" and 
add respective stuff for your favorite *BSD.

Er, not quite. :-) There are still a few things to be done, which otherwise 
would annoy some of our contributors, and ATM real life is interfering a 
bit...

CU, Ingo
