Where's glaux.dcu?

Hi everybody!

Like a lot of people, I’m using NeHe’s OpenGL tutorials, but with Delphi 7. I’m downloading the version for Delphi, but when I try to run the application, I always get the fatal error “missing file: glaux.dcu”.

What is this file (where can I get it?), and what does it mean? I’ve already got glaux.dll
