plugins/video/canvas/wxgl/GLWXDriver2D.cpp from CVS

In an effort to build on my Gentoo distribution, I noticed that the build fails on:

Code:

plugins/video/canvas/wxgl/GLWXDriver2D.cpp: In member function `virtual void*
csGraphics2DWX::GetProcAddress(const char*)':
plugins/video/canvas/wxgl/GLWXDriver2D.cpp:123: error: `glXGetProcAddress'
undeclared (first use this function)
plugins/video/canvas/wxgl/GLWXDriver2D.cpp:123: error: (Each undeclared
identifier is reported only once for each function it appears in.)

I found an open bug on the SourceForge bug list that appears to address this very issue. I am very interested in resolving this. How can I help? Is this the right forum to ask this question?
