problem starting office

[AN]

I recently installed openoffice 2.2 via pkg_add.  When I try to start the 
program, I get the following response:

[root at R51 /usr/local/openoffice.org-2.2.1/program]# ./soffice
no suitable windowing system found, exiting.


I am running Gnome 2.18.1 on FreeBSD 6.2 stable.  I am not sure how to 
troubleshoot this, please advise what other information can help solve 
this.  Any help is appreciated.

TIA
