Well, a while back, OOo and LOo wanted more than 8Gbs.  It wasn't my 
need but what portage looked for.  Then someone did some changes and 
reduced that need and it worked.  From my understanding, there was some 
code clean up that helped in that.  I think it looks for 6Gbs now.  From 
the ebuild:

CHECKREQS_MEMORY="512M"
CHECKREQS_DISK_BUILD="6G"

It used to be more than that.  If it didn't have enough, it stopped.  
Even when I would override that setting, it would still run out of space 
more often than not.  As a matter of fact, I still have the command in 
my freq used commands file that I used to fix it:

mount -t tmpfs -o size=12g tmpfs /var/tmp/portage
