Firefox Launch Problems

[Christopher Riker]

I am trying to get firefox installed in a new installation of Gnome  
under MacPorts 1.4.3 OS 10.4.9 XCode 2.4.1.

I have installed firefox-x11 using the command line with the -gnome  
switch at the end. Sure enough, it appeared in the gnome menu.  
Launching from gnome, however, resulted in no apparent action.

 From the X11 terminal, issuing a ./firefox while in the /opt/local/ 
bin directory seems to start a launch. It returns this error though:

/opt/local/lib/firefox-1.5.0.1/run-mozilla.sh: line 424: 20231  
Illegal instruction     "$prog" ${1+"$@"}

Is there a problem with the current firefox-x11 or am I doing  
something wrong?

Thanks!
