Comment (by ryandesign):

 Replying to [comment:22 fmw42]:
 > Question:  Why did I get the message that opencv4 needed cleaning when I
 had removed every one of my ports.

 Uninstalling installed ports and cleaning work directories of in-progress
 builds are two separate things.

 > I do not understand why I could not install py39-opencv4 before.

 Neither do I.

 > I guess there was a conflict with one of the ports previously installed

 Yes that could be.

 > and the previous attempts to install py39-opencv4 did not overwrite that
 port with the needed version or dependencies.  Perhaps the conflict was
 with OpenEXR. Or perhaps py39-opencv4 was the issue.

 py39-opencv4 declares a dependency on openexr. Therefore when you try to
 install py39-opencv4 MacPorts will ensure openexr is up to date first.
