Yes, you can get 'pure 64' systems (think Red Hat).
And you can 'fix them' by installing the hybrid 32-bit libraries, but I'd rather stay away from it.

CentOs 6 using regular repo used both 32bit and 64 bit libraries - seamlessly.

There is no reason to "fix" anything in modern linux distributions.

There once was, however this is no longer a factor.

I'll expand *your* question!
Are there any *pure* 64-bit OS options out there? Beyond a linux from scratch build, which I have currently that is still pure 64-bit, what is there?
every distro I know of has 32-bit libraries band-aided on to make some 32-bit that refuses to die run.

Well, I'll expand the question...
Performance and memory access considerations aside, the reason why I have
always 'gone 32' is because applications availability. Back when, flash was
the limiting factor because it was a PAIN to run it in 64 bits (if at all
possible).
And some other things...
For years, I've been lazily sticking to 32 bits to avoid potentially
problematic issues. Now, if that landscape has changed, and
application-wise 32 and 64 bits are irrelevant, I'd certainly like to
convert to 64.
Question is (again, performance and memory access considerations aside):
What are the potential problems of running on a pure 64 environment for as
long as you stick to apt-get (or yum)?
