Maybe it's installed, but not in your path. try typing 'whereis gvim' at CLI - obviously without the quotes - if it gives you a path (actually I don't seem to have it, no response to the command (& I really like vim anyway

), but ymmv) then type that path eg. /usr/etc/gvim or whatever your shell returns - if still no joy ie. if it's there but you get 'can't open' error, check the permissions on the app:
ls - l /whatever/the/path/is
if it's only executable by root you need to change permissions (as root) before you can use it (as user) eg su then chmod 755 /whatever/your/path/is/to/gvim
Hope this is of some help

PS If none of this works and you really long for a GUI text editor you could always try calling xemacs instead (pax! pax!)
