Potentially, a patch should be made to the makefiles and submitted back to the project maintainer. Hopefully, we can get the port working anyway.

Remember to use WikiFormatting and to preview before you submit, and to fill in the Port field.

The actual error, which you cut from your output, is

ws/NetworkAccessManager.cpp:22:23: error: lastfm/ws.h: No such file or directory

I'll attach a full log.

Confirmed that turning off parallel build fixes it, so that's what I did in r70181. If you'd like to pursue creating a patch to fix this in the sources to allow parallel builds, and submitting this upstream for inclusion in the next version, feel free to do so, but disabling the parallel build is enough for the purposes of MacPorts right now.
