the first build-error i got was with gst-buzztard because i hadn't installed fluidsynth because it wasn't mentioned in the documentation:

" it seems that the dep fluidsynth is forgotten to mention in the documentation, i got a compile error with gst-buzztard: ../../src/fluidsynth/gstfluidsynth.h:33:24: error: fluidsynth.h: No such file or directory"

So after i installed that it built fine, the next error was with buzztard itself, this one:

" creating bt-edit-scan
gtk-doc: Running scanner bt-edit-scan
(lt-bt-edit-scan:15220): Gtk-WARNING **: cannot open display:
Scan failed: 
make[5]: *** [scan-build.stamp] Error 1
make[5]: Leaving directory `/usr/src/buzztard-svnr1712/docs/reference/bt-edit'"

after i removed the enable-gtk-doc-flag it compiled fine, all the other modules compiled fine with the gtk-doc flac enabled.
