为了测试3D加速效果，安装了如下ports
/usr/ports/graphics/mesa-demos
glxinfo glxpears等测试程序都是在这个ports中，但是在make时，在一些测试程序中报错无法继续进行下去，主要是一些 ...MESA 函数，查看 /usr/local/include/GL/glx.h 文件，里面也不存在对应的函数，费了一番周折进行了修改，但是整体编译还是不成功。
细究了一下 GL 对应的头文件，发现在nvidia驱动安装以后，nvidia不同程度的覆盖了原来系统的MESA3D的一些文件。
both libGL-7.0.1 and nvidia-driver-100.14.19，也就是两个ports都包含这个，从日期上看，nvidia的覆盖了原来的。
libGL-7.0.1的文件列表如下：
Information for libGL-7.0.1:
Files:
/usr/local/include/GL/gl.h
/usr/local/include/GL/glext.h
/usr/local/include/GL/glx.h
/usr/local/include/GL/glxext.h
文件列表如下：

Files:
/usr/local/include/GL/glu.h
/usr/local/share/doc/NVIDIA_GLX-1.0/gl.h
/usr/local/share/doc/NVIDIA_GLX-1.0/glext.h
/usr/local/share/doc/NVIDIA_GLX-1.0/glx.h
/usr/local/share/doc/NVIDIA_GLX-1.0/glxtokens.h
我想这可能是mesa-demos没有安装成功的一个原因，但没有具体的确定
小节：OPENGL的库还是蛮复杂的，感觉里面也是有不少的陷阱
附上nvidia-driver的文件列表，以后参考:-)
