How to enable hardware support for libEGL for Tegra 2 Linux?

Question

I am trying to run my OpenGL ES application Ubuntu 11.04 installed on Harmony developer board (Tegra 2), however when I use packages:

libegl1-mesa, libegl1-mesa-dev, libegl1-mesa-drivers
libgles2-mesa, libgles2-mesa-dev

application reports:

libEGL warning using software fallback

I was getting the same message when I tried to start example provided in package mesa-utils-extra called /usr/bin/es2gears but after updating drivers:

export LDK_ROOTFS_DIR=/
cd Linux_for_Tegra
./apply_binaries.sh

and creating symlinks like in "Tegra Linux Driver Package Developers Guide"

mv /usr/lib/libEGL.so /usr/lib/libEGL.so.1
mv /usr/lib/libGLESv2.so /usr/lib/libGLESv2.so.2
ln -s /usr/lib/libEGL.so.1 /usr/lib/libEGL.so
ln -s /usr/lib/libGLESv2.so.2 /usr/lib/libGLESv2.so

I am able to start es2gears using hardware acceleration (2x faster).

My question is where can I get development packages that use appropriate libEGL.so and libGLESv2.so libraries so I can compile my application?
