compiling Firefox/Seamonkey/Thunderbird

[Bob Melson]

For the past several months, whenever there's been an update to Firefox, 
Seamonkey or Thunderbird compilation has failed at what appears to be 
the same place in each of the products (what I show below is from an 
attempted compilation of Firefox, but could as well be for the others). 
  I've looked at /usr/ports/UPDATING and have made sure that sqlite has 
been compiled with the necessary flag and have, as well, tracked down 
ports/200853 (which I admit I don't entirely understand).

My question, then, is what must I do to successfully compile any one or 
all of these applications?  I'm pretty sure it's a matter of user 
head-space and timing, but I really haven't a clue, so any help would be 
very much appreciated.
