[Denemo-devel] install help required

[wjm]

Greetings,
When installing Denemo the configure program exits with an error message:-
checking for FLUIDSYNTH... no
configure: error: Package requirements (fluidsynth >= 1.0.8) were not met:
No package 'fluidsynth' found

However, the system command 'which fluidsynth' gives the following:-
/usr/bin/fluidsynth

Its version number is:-
FluidSynth version 1.1.5

Can you provide a reasonably full help for this, please?
You are dealing with someone with no familiarity with the inner workings 
of source compilation. :)

The system here is:-
Ubuntu 12.10
AMD64

Many thanks,
Bill
