Unable to build Firefox 3 from ports

[Alex]

Hi Guys,

The subject says it all. I am running 7.1-Stable/i386
Portsnap from Sun Feb 15 01:00:52 EST 2009

The build from ports starts off ok, the dependencies are compiled and 
installed, however once the compilation of the firefox source starts, 
its not long before it dies:
