opengl.dll missing from Windows 98 ?

I’ve recently started using OpenGL SDK based on the information that opengl.dll is present on all Windows system from 95 (OSR2) onwards. Now that I moved my application from Windows NT onto Windows 98 I realized (in horror) that opengl.dll is missing.
Is opengl.dll really not preinstalled on Windows 98 or could there be another reason why it is missing from some of the Windows 98 installations?

look for opengl32.dll
that is what you get

thanks mr x, you just allowed me to have the weekend off.
