It looks like I can tell whether a port is installed and get the version of a
installed port in question via the MacPorts registry API. But I do not see any
docs on how to use the MacPorts registry API in a Portfile.
Once I know whether a port is installed and its version number, I should be
able to use conflcts_build-append in a tcl block in the Portfile (e.g. in a
pre-configure{} or pre-build{} block. pre-configure{} probably makes the most
sense).
Can someone point me to some docs on how to use the MacPorts registry API or to
some example Portfiles?

Subject: Need Help with the "conflicts_build" PortGroup
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?
