Activating multiple versions of a port.

[David Strubbe]

Sorry, you can't do that either. Only one version of a port may be active
at a time. MacPorts does not in fact record the specific version of the
library used in building a port, and the point is that the absolute path is
generally the same for the files of different versions of a port, so there
is nowhere else to put these files if two were activated.

If you are thinking that ffmpeg was working with a particular version of
x265 but not with the current one, then you can activate in sequence each
version of x265 you have installed, and see which make ffmpeg work and
which do not.
