THANKS! (and an error compiling amarok)

Hi ! First of all, thanks for making trinity. I works very well, and finally I found the lightweight DE that I was looking for. So I started compiling apps, and started with amarok. I downloaded from trinity's server (meaning, not from git). Then cmake . and make. It gives me this error when it tries to compile libamarok.so.0.0.0: /usr/lib64/gcc/x86_64-slackware-linux/5.3.0/../../../../x86_64-slackware-linux/bin/ld: cannot find -ltagmp4-static collect2: error: ld returned 1 exit status amarok/src/CMakeFiles/amarok-shared.dir/build.make:3012: recipe for target 'amarok/src/libamarok.so.0.0.0' failed make[2]: *** [amarok/src/libamarok.so.0.0.0] Error 1 make[2]: Leaving directory '/kubuntu/home/dvadell/tde3/build/amarok' CMakeFiles/Makefile2:199: recipe for target 'amarok/src/CMakeFiles/amarok-shared.dir/all' failed make[1]: *** [amarok/src/CMakeFiles/amarok-shared.dir/all] Error 2 make[1]: Leaving directory '/kubuntu/home/dvadell/tde3/build/amarok' Makefile:127: recipe for target 'all' failed make: *** [all] Error 2 So I unistalled KDE4 (I didn't need it now :) ) but the error remains. If anyone could help me, I would be very grateful. Again, thanks for trinity. Cheers, -- Diego.
