Error using libchk

[Gerard Seibert]

I recently ran 'portsclean' to clean up my ports system. It recommended that I 
install 'libchk' which I subsequently did.

The problem is that when I attempt to run 'libchk' I receive the following 
error message:

	env: ruby: No such file or directory

I have read the manual, however I still can not find a way to run this 
program, nor have I been able to decipher this error message.

Any assistance would be appreciated.

Thanks!
