Hm, packages.ubuntu.com confirms that there's a gl.h file in mesa-common-dev, so closing this bug is fine.
(I know the headers went missing after upgrading because OpenGL programming assignments that compiled fine before could no longer find them, but I've since then had to give up on testing Dapper.)
