[Mono-list] Uninstall Mono on OSX

[oplus]

Hi,
I think that I have both the installer version (.dmg) of mono and the 
fink version and it is causing errors starting monodevelop:

Loading error, please reinstall :
System.ComponentModel.Win32Exception: Cannot find the specified file

I'd prefer to keep the fink version -  how can I uninstall the dmg pkg 
version?
