DeVeDe menu generation requires a "/usr/local/share/devede/silence.wav" file which does not exist, causing the menu generation process to abend/abort. The source file DOES exist, but for some reason it is in source "pixmaps" directory. The install process does not include this particular file, hence the missing "silence.wav" file.

Fix: 

Add following line (or something like it) to "do-install" block in the devede port Makefile:

${INSTALL_DATA} ${WRKSRC}/pixmaps/silence.wav ${DATADIR}
