Topic: Installing scratchbox emulator

I've been trying to follow the wiki to install scratchbox, and run into the missing emulator issue.  I tried to follow this forum post but I still don't have a working emulator, although the compiler seemed happy to build "hello.c".  When I run it, I get:

[sbox-Chumby: ~/hello] > ./hello
/scratchbox/tools/bin/misc_runner: SBOX_CPUTRANSPARENCY_METHOD not set

which is not a surprise, since I basically shrugged and pushed passed that part of the configuration to see how much I could get working.

Anyway, the WiKi seems to be falling out of date and is getting confusing. What emulator should I download? How do I install and select it? 

TIA
