Need Help with the "conflicts_build" PortGroup

[Robert Kennedy]

I am upgrading a port where only certain installed releases will prevent the building of the upgraded port.

Is there a way to use conflicts_build from the conflicts_build PortGroup with only certain installed releases?  Maybe it could be done by using a pre-build {} tcl block?

Is there a global variable available that is set to the installed version number?
And is there an easy way to tell if a port is already installed before upgrading?

Rob
