This works _almost_ perfectly for me. Two changes I had to make:

1: Gem looks for the sun compiler in /opt/studio/SOS11/SUNWspro, but on my
system it's in /opt/SUNWspro - I _think_ that's the default - at least, I
don't remember changing it. I made a symlink and it worked fine.

2: When I ran mongrel, /opt/csw/lib/ruby/gems/mongrel-1.1.5/lib/http11.so
could not find libucb.so to link against. I had to set
LD_LIBRARY_PATH=/usr/ucblib, then everything was fine 

I guess both of these could be fixed, if appropriate, by setting overrides
on CC and LD_FLAGS in rbconfig.rb
