Sort of. According to example 4.7 in 
http://bitbake.berlios.de/manual/ch04s02.html this needs setting in a 
.conf file not in the .bb file. I've set it in local.conf and bitbake 
now builds the right version, though it looks like I've got some 
cleaning up to do as linphone still seems to try linking against the 
wrong version. This doesn't seem like the best place for dependency 
information though since it separates the dependency information from 
the package that has the dependency. Can I put this in the .bb file, or 
is there another config file I should be using?
