Subject: Re: examples using reliable-msg gem?

I figured out the problem. In the queue-manager.rb file the author  
sets up an ACL for the DRbServer. The acl contains "allow 127.0.0.1".  
For whatever reason, OSX binds to the port using IPv6 so the ACL  
denies any connections coming through the loopback.

There are two fixes. One workaround is to eliminate the ACL.

The second workaround is to change the acl to read "allow 127.0.0.1,  
allow ::1" where "::1" is the localhost equivalent for IPv6  
(alternately, change 127.0.0.1 to localhost). After this change inter- 
process calls work.

I hope the next person who runs into this problem finds this note. It  
only took me 2 days to figure it out. :-)
