After emerging mt-daapd-0.2.3 successfully it did not start, because it was unable to find /usr/local/lib/libgdbm.2.dylib. I have gdbm-1.8.3-r2 installed, so I made a symlink to /usr/lib/libgdbm.3.0.0.dylib and now it works.
See resolution above.
that's no solution. Flameeyes do you have an idea why it looks in /usr/local?
I see that if the original comment is right, the soname changed, probably /usr/local/lib is the last try and that's reported.
this is a wrong linking problem.
