[rancid] unable to login on devices via clogin

[Arshad Ali]

HI,
I am unable to login to any network device through clogin via rancid user and root user and gets following error. 
login error: Error: can't read "22": no such variable.

I can see same issue with all the devices. I am not expert in linux. 
Is it related to permission on ".cloginrc"?
I checked logs and found following error. 
svn: E000013: Can't open file '/var/lib/rancid/PerthIX/.svn/pristine/b4/b40db22fb4aba04068988ff2f52eb9adc129120a.svn-base': Permission denied
