Error: no known VMs. (check for corrupt jvm.cfg file)

I just upgraded my Coldfusion 9 server (multiserver edition on 64 bit Linux) to 9.0.1. Now when I try to start I'm getting the error:

Error: no known VMs. (check for corrupt jvm.cfg file)

I looked at the jvm.config file and java.home is pointing to the correct place (checked that based on other people's problems with this error)

This was on my dev server. On my QA and Prod servers I installed 9.0.1 from the start. So I tried copying my jvm.config from one of those machines but I still get the same error.

Anything else I can do to diagnose this error?

Strange. The jrun executable was a 32 bit program. I copied jrun from one of my QA servers and I am back in business.

Yes, due to such mismatch, VMs can't be loaded..

Any idea why the 64bit update contained a 32bit version of jrun? It seemed funny that I found no indication via google search that anyone else has reported that problem.
