I didn't write the manual, so save your hubris for whoever did.  I just 
followed its instructions, I ate the dog food.

The test has nothing to do with installing from a pre-existing install.  The 
test was getting a current gentoo stage tarball with a current portage 
snapshot up to date, stage1 -vs- stage3.  Nothing was unmasked either.  
Were you are pulling that from is beyond me.

Running an emerge -e system does not magically switch you over to the new 
gcc, it would uselessly recompile the entire system with gcc 3.3.4 again.  
Hence the need to READ AND COMPREHEND the instructions in the gcc migration 
guide, which was plainly announced in GWN at the time.  If you don't 
believe me, go troll around the forums a little and try to help the poor 
saps who didn't realize they needed to follow that guide.  Even half of the 
ones who did read the guide completely dorked up their running boxes.

If you actually downloaded a "pristine" stage1 or a stage3 tarball you might 
notice that there are, in fact, packages already present in world.  Glibc, 
gettext, nano, gzip, and linux-headers.  Not that that matters one iota to 
this conversation, but you need to get your own facts straight before 
running around calling people idiots.

The difference in doing from stage1 instead of stage3 is you don't have to 
go through a gcc migration to prevent your build from being unusable.  You 
also go through 1 gcc upgrade (gcc 3.3.5 -> gcc 3.4.4), not 3 (3.3.5 -> 
3.3.6 -> 3.4.4).  We are talking reality here, not fantasy.
