Interesting that there is another guy running Squeak under Solaris.

Which version of the VM sources you are talking about?
I have 3.9-8 running for quite some time on my Blade 2000.
Although I haven't used sound yet.
I have good experiences with Sun's CoolTools gcc for SPARC systems.
This is a gcc-4.0.4 frontend with a SunStudio 12 code generator.
The code runs at least twice as fast as with a plain gcc-3.4.3.

Did you manage to build libffi-2.0? This library is part of gcc-4.2.1.
AFAIK it is necessary for Squeak's FFI. I have only an old libffi-1.2.0 that
has some Solaris bugs. So I don't have FFI which is needed for some 
interesting
packages (e.g. ODBC).
