/etc/vimrc references cscope and will call it if you have a cscope.out from a
previous install which had cscope installed.  This leads to errors like
[katzj@bree anaconda]$ vim
Error detected while processing /etc/vimrc:
line   32:
cs_read_prompt EOF: Illegal seek
E609: Cscope error: sh: /usr/bin/cscope: No such file or directorysh: line 0:
exec: /usr/bin/cscope: cannot execute: No such file or directory
Hit ENTER or type command to continue


To reproduce, just touch cscope.out and remove the cscope package
