Looking at the previous posts, I can see that she failed to install 
recordclass because it couldn't find a compiler.

When I tried to install recordclass, pip downloaded the sources and 
compiled them.

I then uninstalled recordclass.

I updated pip, which didn't need a compiler.

I installed recordclass again. Pip downloaded the wheel, and it didn't 
need a compiler.

So if she's saying that updating pip requires a compiler, then there's 
something screwy with her system.
