SPARC v9 is 64 bit. My printed SPARC v9 spec is from 1994.
In Solaris usually the kernel is 64 bit, libraries are available in 32  
and 64 bit
(64 bit in a sparcv9 sub directory) and most applications in 32 bit.
As long as an application doesn't need a 64 bit address space there is  
need to have it 64 bit because unlike x86 / x64 you won't gain speed  
in 64. The prerequisites I mentioned are available in both depths (gmp  
and mpfr passing
all checks). Only libffi has many failing checks at the moment.
My plan is to create a working squeak VM first and then care for some  
improvements on
libffi and one or two packages. At the moment I am using Sun's GCC4SS  
as it generated
faster executables but it will make it necessary to at least install  
the appropriate run time
libraries. So I also consider to create a version that only depends on  
the system supplied

Thanks for the pointer. I son't know yet whether it will be necessary  
to create a 64 bit
version. It seems as if most people are still satisfied with 32 bit  
and on SPARC this will
be faster.

I still don't have experiences with VMMaker. It's a little bit  
confusing to have
sources on squeakvm.org and also VMMaker. I will try it out as soon as  
I have
a running squeak on Solaris...
