error: HiddenLine.h: No such file or directory

[Roger H. <rog...@mi...>]

Hi, I just did an anonymous checkout of the latest Quesa source and  
tried compiling the QuesaCocoa project.

It gives this error:

/Users/roger/Desktop/quesa/quesa anon 21052007/Development/Projects/ 
Mac/../../Source/Core/Support/E3System.c:53:24: error: HiddenLine.h:  
No such file or directory


Why are plug-in renderers being referenced directly inside E3System.c ?
