Subject: Re: get process id by using it's name.

I know the sysproc library supports very good interface for this kinds  
of jobs.

but, sysproc doesn't support aix platforms.

$> rake test
(in /home/jykim/sys-proctable-0.8.0)
checking for rb_pid_t in ruby.h... yes
This platform not currently supported.  Exiting...
.....

I need pure ruby lang based libraries or all platforms ported things :)

gamsa haeyo~
