Comment (by petr@…):

 I see this was actually implemented (but the reference is missing) by
 vince@ in r121188.

 However, I would argue that this solution is not ideal. I'd expect that in
 general (with very few exceptions) below /opt/local or more exactly
 ${prefix} files are manipulated and tracked by Macports, as macports in
 general would not touch anything outside ${prefix}.

 So we would rather (1) create a port for the ECW library, so that it can
 be easily removed again. If the distfile cannot be fetched automatically
 for technical **or** license reasons, the distfile will need to be placed
 by the user, just like (py-nio or ncarg). (2) As an alternative, we could
 ask users to install it in some well-known location **outside** the
 Macports tree, for example `/opt/lib/ECW` or `/opt/ECW/lib`. But I'd
 prefer (1) if this is feasible.
