Hallo Benny!

 BP> gentoo have disabled multilib on 64bit

What took them so long?  I briefly had a multilib going when I first got my 
hands on a amd64 and went pure 64 bit after that on a quad core xeon.  That was 
around 15 years ago and the only distribution talking about pure 64 back then 
was fedora.  The "Cross Linux From Scratch" people were the only ones I was 
aware of that did more than just talk about it.

As far as raspbian is concerned, there is a port called pi64 which is as close 
as it gets to an official raspbian.  I haven't tried it myself as I have issues 
with people who purposely degrade hardware all in the name of so-called 
compatibilty.  The raspbian people are no better than what Bill Gates did way 
back in the early 1990's with 16-bit dos on 32 bit cpu's.  It took MS a decade 
before finally getting rid of that lame idea and by that time the x86_64's were 
rearing their ugly heads and ot took them another five-ish years to finally 
catch up.

Putting a 32 bit operating system on a 64 bit cpu is shameful and disgraceful 
methinks.

Het leven is goed,
