--- Comment #5 from Ryan Schmidt wine-2013@ryandesign.com --- The reason why we force INSTALL='/usr/bin/install -c' may no longer be applicable so I could look into changing MacPorts base to no longer do that. However, I don't understand why setting INSTALL to a valid install program causes a problem for wine.
