Well, how exactly did you go about installing Wine? If it came installed with Redhat, it's most likely installed as an RPM. To find out, try this (from a terminal):
rpm -qa | grep wine
If it gives you a reply, like "wine-2002xxx.rpm", then it's installed as an RPM.
The only way it'd be installed from source is if you installed it yourself, so if you don't know anything about that, then it probably isn't installed from source
