[Rails] Rails 3.1.0.rc5 server won't start

Hi,

Have hit a problem upgrading rails to 3.1.0.rc5 on the server (Centos
5.5). No problems locally an a mac.

After deploying with capistrano and restarting the server, I got the
following error from passenger:

"Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs
for a list of available runtimes. (ExecJS::RuntimeUnavailable)"

I went to the url mentioned, and ensured the following:

execjs gem is installed (1.2.4).
node is installed (0.4.8).
coffee-script is installed (1.1.2).

The problem remained.

I then did some googling and found solutions that suggested including
therubyracer gem (which basically does the same as node I guess), so I
tried that and got a 500 error when accessing the site, removing it
takes me back to the JS runtime error.

Anyone had anything similar, or got any suggestions?

From what I have read, it appears that this will be fixed in the 3.1
final release which won't rely on a javascript runtime engine during
start up, and I would like to continue with 3.1 so I can continue with
sass and coffee-script during the lead up to the final release, so any
help is greatly appreciated.

Thanks

Paul
