Denemo won't compile without package samplerate -but where is it?

I'm using Ubuntu 10.04 LTS. Canonical does not provide updates for the music notation program 'denemo-0.8.10' - which is now well out of date - so I've tried to compile the latest version (denemo-0.8.20) by downloading sources from the GIT repository git://git.savannah.gnu.org/denemo.git.

I first ran $sh autogen.sh as suggested on the Denemo web-site in relation to an Ubuntu/Debian compile-and-install and then $./configure.

'configure' complained as follows:
--------------------------------------------
checking for samplerate... configure: error: Package requirements (samplerate >= 0.1.2) were not met:

No package 'samplerate' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables samplerate_CFLAGS
and samplerate_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
------------------------------------------
I've installed the package 'samplerate-programs', but this hasn't helped. Trawling the internet hasn't shown where 'samplerate' is kept: still less if it were to be found whether or not it would be suitable in the Ubuntu environment. Also, $sudo apt-get install samplerate doesn't yield any results either.

Further, the above suggestions from 'configure' are singularly unhelpful since the man pages of pkg-config offer no suggestions as to how and where these environment variables for 'samplerate' are to set.

So, any suggestions as to how to get past this particular instance of dependency hell would be much appreciated! - Gordon Oulsnam
