[StarCluster] StarCluster newbie question

[Boris Hayete]

Hello!

I'm trying to configure starcluster as per instructions here:

https://www.bioconductor.org/help/bioconductor-cloud-ami/#first-time-steps

I've gotten reasonably far: when I run starcluster start smallcluster, 
it runs for about 30 seconds before crashing with the following obscure 
error.  Any tips on where to start?  I thought it was related to region 
setting but everyting *seems* fine.
