I have created a Solaris-10 SPARC package from Squeak-3.10-5 sources  
with minor patches
in the SocketPlugin for UNIX. This has no closure support yet and I  
expect FFI will not work because
of the actual state of the libffi that I used. It depends on the  
runtime libraries for gcc-4.3.2 from
Sun (SUNWgccfss432_runtime.tar.bz2 file downloadable from Sun).

The next step is to get some experiences with VMMaker and to create  
closure sources with it.
Some simple speed test results for my momentary SPARC machines (taken  
with Cuis):

" Blade 2500 (2*1,6GHz UltraSPARC-IIIi): "
0 tinyBenchmarks '97190584 bytecodes/sec; 4133412 sends/sec'

" Blade 2500 (2*1,28GHz UltraSPARC-IIIi): "
0 tinyBenchmarks '77015643 bytecodes/sec; 3275651 sends/sec'

" Blade 2000 (2*1,2GHz UltraSPARC-III)"
0 tinyBenchmarks '73101085 bytecodes/sec; 2990128 sends/sec'

" E250 (2*300MHz UltraSPARC-II):"
0 tinyBenchmarks '19643953 bytecodes/sec; 761256 sends/sec'
