You may want to look into the buildpkg option in make.conf.  It builds
them automatically for you as you emerge things.  I've had a close call
or two so I have had that set for many years now.  If you do set that,
remember to use eclean-pkg on occasion if you start using a lot of hard
drive space. 

You also may want to look into eclean-dist too.  ;-)
