MacPorts XCode Installation

[Michele Venturi]

I have the required libraries in /usr/lib/swift too,but MPV is looking for
them in /opt/local/lib,so it doesn't find them:

otool -l $(which mpv)
...
cmd LC_RPATH
cmdsize 32
path /opt/local/lib (offset 12)

Should we change RPATH or add symbolic links?
