configure: error: Package requirements (xf86driproto >= 2.1.0) were not met:
Requested 'xf86driproto >= 2.1.0' but version of XF86DRIProto is 2.0.4
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables DRIPROTO_CFLAGS
and DRIPROTO_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
