which version of ruby is needed for CloudFoundry?
===

when I try to manager my mysql service by vmc tool. I got a error like below:
<br>

XXX@XXX:/media/big/workTree/LinuxJava/enochfallen$ vmc tunnel cucgp --port 9999 mysql

ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 0

Is that some trouble with my ruby version?I just install it with apt from ubuntu source.
At the end, I make apologies for my poor English.
