error during stage configure of xserver

[terry_orange]

checking for GL... configure: error: Package requirements (glproto >= 1.4.9 gl >= 7.1.0) were not met:

No package 'gl' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables GL_CFLAGS
and GL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
