Yes, both packages can be installed at the same time.

The packages are also delivered in both 32bit and 64bit 
(but only Intel/AMD, not SPARC).

The packaging uses "mediators" which is something that can be used to have
multiple versions of some system installed.  

For example if I have squeak-4 installed (medatior version: 4),
and then install squeak-5 it changes version and implementation:

Changed mediators:
  mediator squeak:
           version: 4 (system default) -> 5 (system default)
    implementation: None -> cog-spur (system default)

So the mediator squeak is a property of the packages,
to have multiple "builds" or "variations" of the same package installed.

I am not building debug or profile VMs, but for example if a debug VM
would be built, then it could set the mediator to some value,
so that both the non-debug and the debug VM can be installed together.
