Hello all, I now want to use vgui in my project, but when I run the example in  core/vgui/examples/example_text_windows, an error occured:

freeglut  ERROR:  Function <glutBitmapCharacter> called without first calling 'glutInit'.
vgui::uninit called

My settings are : Ubuntu 7.10, freeglut 2.4.0. gcc 4.1.2
After some google, I understood this error a little better:

the 2.4.0 release announcement at 
| freeglut.sourceforge.net:
| "Users should note a new incompatibility with GLUT, in which GLUT
| allowed the application to call some functions before 'glutInit' was
| called. This is contrary to both good programming practice and the GLUT
| documentation, and the new 'freeglut' enforces the initial call to
| 'glutInit'".
It seems that the freeglut of version 2.4.0 results in this error. But how can I fix it?
