Yeah, same here on a Sun 4/50.  My question was more along the lines of;

  'If Mozilla won't compile, why is it in the pkgsrc?  And if Mozilla
  does compile, why is there no pkg for it?'

The problem with the "segmentation error" is caused by one of the utilities
Mozilla uses to compile itself - perhaps there is a patch for this in a
newer version of Mozilla?

I'd really like to get Mozilla running, mostly because of IPv6 support and
will be playing with it again in the coming weeks.  If I get a positive
result I will be sure to submit patches etc. to this list.
