If you are trying out OpenOffice with X11, then the following tip may be helpful. Supposedly Apple's X11 will let X11 apps access OSX fonts. However, in practice, most don't use xft which is what allows this to work. To get OpenOffice to work with OSX fonts you have to do the following:
% cd /Applications/OpenOffice.org1.0.1/share/fonts
% /usr/local/bin/fondu /Library/Fonts/*
Someone told me this, I can't claim to have come up with this hint on my own. I figured others may have been having problems with this. I've not figured out how to get AbiWord to work with OSX fonts yet. However xterm and some applications will work. i.e. the following works:
% xterm -fa Monaco -fs 11

Editor's note: I have not tested this hint myself as I haven't had a chance to install OpenOffice yet...]
