"failed to install" app in iOS simulator, but works fine in Rho simulator

I am testing a Rhodes app an a Mac (OSX 10.9, Rhodes 3.5.1.12), and it runs fine in the Rho Simulator.  However, when I try to run the app in the iPhone Simulator (6.1), it doesn't run.  The app icon shows up, and if I click to run that way, it tries to run but crashes on init. 

The most promising message I found on the command line was:

[DEBUG] Session could not be started: Error Domain=DTiPhoneSimulatorErrorDomain Code=1 "iOS Simulator failed to install the application." UserInfo=0x100138800 {NSLocalizedDescription=iOS Simulator failed to install the application., DTiPhoneSimulatorUnderlyingErrorCodeKey=-1}

However, this did not make sense to me, since the app does seem to be copied to the simulator directory (~/Library/Application Support/iPhone Simulator/6.1/Applications/{guid}/).  Also, the iPhone simulator still comes up, and the app icon is present and does attempt to run. 

I looked at the system log and crash report (rho log had nothing in it), and what I found didn't help.  The crash report shows the app raising method_missing during RhoRubyInitApp.  

I created a new Rhodes app with minimal code (single Rhodes model), but the same thing happens: it works fine in the Rho Simulator but crashes in the iPhone Simulator. 

Has anyone experienced anything similar?  I have included the relevant parts of the system log and crash report below.  Also, I am building and running from the command line, if that matters.
