There has come some new build guides, and now they are for OOo2(beta) :-)
Linux (x86)
http://tools.openoffice.org/dev_docs/build_linux.html
Solaris
http://tools.openoffice.org/dev_docs/build_solaris.html
DarwinPPC/MacOS X
http://porting.openoffice.org/mac/build_680_X11.html
Windows
http://tools.openoffice.org/dev_docs/build_windows_tcsh.html
A good thing about the Windows guide is that it gives a more complete
list about utilities that are needed...
