Got a bit further,

have libprojectm built

have libprojectm-qt built

just getting an error on linking the final part

Linking CXX executable projectM-pulseaudio
/usr/local/lib/libprojectM.so: undefined reference to `glXQueryVersion'
/usr/local/lib/libprojectM.so: undefined reference to `glXGetProcAddressARB'
/usr/local/lib/libprojectM.so: undefined reference to `glXGetClientString'

Its bound not to work straight away once i get past this as i have had to comment out a few bits to get it to build at all. But at least once i can get an executable i should be well on the way.
