Hi,A little while back I got OpenOffice.org 2.0 to work on OpenBSD 3.8 snapshots. I didn't use the linux proc and I didn't install the RPM's.
I used rpm2cpio to convert the RPM's, then I used cpio to extract the achives.
I enabled linux emulation and then just ran the soffice.bin file.Everything works perfect on my machine. I have done some testing with previous written documentation in OpenOffice.org 1.5 and everything has been working perfectly.
Best regards, Rico
