The 'Weird' part is amarok builds just fine on my system. All I did was remove the tunepimp dependency. tdenetwork also builds fine. Maybe there are still some growing pains in gcc 4.7.1 and Slack/Arch/Fedora all have varying patches/fixes applied to get around it. Dunno, but builds here/not there should at least be explainable...
I thought I was building amarok with no musicbrainz dependency, but now that I look at my configuration options I see nothing explicitly doing that. I got confused with my tdemultimedia build script, which has such an explicit option.
Which amarok build option do you use to disable musicbrainz/tunepimp?
