Comment (by Polyergic):

 Took a few tries to apply the patch properly; eventually did this:

 {{{
 sudo cp ~/Downloads/spectrogram.cpp.diff
 /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/multimedia/kdenlive/files/
 sudo chmod a+r
 /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/multimedia/kdenlive/files/spectrogram.cpp.diff
 sudo nano
 /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/multimedia/kdenlive/Portfile
 ## insert line 43:    patchfiles-append spectrogram.cpp.diff
 sudo port clean kdenlive
 sudo port install kdenlive +docs
 }}}

 And now the build succeeds.
