[rancid] CentOS 6.6, recent upgrade, now all CatOS devices broken

[Brooks Bridges]

Had a system with Rancid installed from the EPEL repos. All switches 
were configured and everything worked great. Someone ran a yum update on 
the system yesterday, and it upgraded the package to 
"rancid-3.2-1.el6.x86_64", which broke all kinds of crap.

The first indication was the Socket module bug, which I got corrected, 
however now all CatOS devices in the network are "down" and cannot get 
the configs pulled from them. After adding a bit of debugging, the logs 
show:

smfits1.domain.com: missed cmd(s): write term all,show port ifindex,show 
module,dir sup-microcode:,dir sup-bootflash:,dir bootflash:,dir 
slot0:,show flash,show running-config,write term,show boot,dir 
slot1:,show inventory raw
smfits1.domain.com - Clean_run is: 0 <--- added debugging statement
smfits1.domain.com - found_end is: 0 <--- added debugging statement
smfits1.domain.com: End of run not found

After many hours of digging, I've determined that the issue appears to 
be that clogin is not properly recognizing the end of the output of the 
commands.

Debug log can be viewed at http://pastebin.ca/3027707 showing this 
behavior when running "show version", where it gets to the end of the 
output from the command and then just hangs there. It appears that none 
of the regexes are being matched when the command prompt pops back up 
after the command completes (perhaps it's only looking for a 'more' 
prompt?).

Since the FTP site still doesn't let you download anything from the .old 
directory (and doesn't show any indication that it's going to be fixed 
anytime soon) I can't get my hands on the old version to compare it 
against. My lack of perl, tcl, and expect skills are quite an obstacle 
here as well.

Any pointers in how to hammer this thing back into submission?
