ubuntu "man glRotate" ?

Question

When on MacOSX, "man glRotate" brings up the glRotate manpage.

On ubuntu, with manpages-dev and manpages-posix-dev insatlled, "man glRotate" doesn't bring up the glRotate manpage (though I can build and compile gl apps).

What am I missing? How do I setup this up?

Thanks
