[vtkusers] Error building VTK: Related to vtkgl.h and OS X

[Neil Gajare]

Hello,

I am in the process of building VTK on Mac OS X, and keep getting
errors with vtkRendering.  A previous error related to OpenGL has been
fixed I believe with help from the user list.

Upon building with those fixes, an error that has been showing up for
sometime popped up just when the build was at 99%.

I am also wondering what the "bash" means, because it just started
showing up in the error printouts.
