Problem with esd.h not found in gnome-libs compile

[richard harding southsomerset gov uk]

     Hi all
     
     
     
     My compile of gnome-libs 0.99.2 from tarball fails with this error
     
     gnome_sound.c31:esd.h : no such file
     
     I have esound 0.2.7 installed in /opt/esound and have added 
     /opt/esound/lib to my /etc/ld.so.conf and /opt/esound/bin to my path 
     in my profile - esd.h is sitting in the include directory 
     /opt/esound/include
     
     Could someone give me some pointers as what I should check next ?
     
     
     thanks in advance for you help
