Only up to a point, though, as Ryan has been pointing out. But in this case
I meant have your Qt4 as a main port, and a subport of that that installs
the symlinks to make it compatible with the existing qt4-mac.

If it can be done at all, it can only be done with actual ports, not
variants. Mostly I suggested qt4-mac-devel because of the implication that
this is the future qt4-mac, and lower confusion for users; the mechanism
for allowing multiple ports to satisfy a dependency only lists the default
port to install if no existing installed port does so; presumably that
would be qt4-mac for now. My hope is that a significant number of ports
depending on qt4-mac already use a path or bin dependency so that ports
like qt4-mac-devel or your backward compatibility shim port (assuming
previous response) could satisfy it if installed.
