There is no option to port(1) that will show this. The buildbot logs 
(which are linked from ports.macports.org) do contain this information; 
for example, <https://ports.macports.org/port/libewf/details/> links to 
<https://build.macports.org/builders/ports-13_x86_64-builder/builds/6392> 
which in the stdio for the "gather archives" step says: "libewf" is not 
distributable because its dependency "macfuse" has license "restrictive" 
which is not known to be distributable.

Of course that's a bit more digging than would be ideal, and the logs do 
eventually get deleted, so getting the web app to remember and display 
this information right on the port details page would be a good improvement.

Also, whether a binary archive is currently available for a port and 
whether one would be made available if the port were built are two 
different questions. Answering the former requires a http request to 
packages.macports.org. To answer the latter, you can use the same script 
that the buildbot uses: 
<https://github.com/macports/macports-infrastructure/blob/master/jobs/port_binary_distributable.tcl>

Generating this information for all ports is not too difficult with a 
little scripting, but does take quite some time.

List which ports do and don't have an archive available (for your 
current OS version and arch):

List which ports are and aren't considered distributable:
