Hi guys!

I was building some blender dependency from source when I realized that compiling fltk the libfltk_gl* library was not generated: apparently configure didn't complain about missing or mismatched software. Glancing into config.log I found the following:

/usr/X11R6/lib/libGL.a(glxcmds.o)(.text+0x2c63): In function `glXGetMscRateOML':
: undefined reference to `XF86VidModeQueryVersion'
/usr/X11R6/lib/libGL.a(glxcmds.o)(.text+0x2c98): In function `glXGetMscRateOML':
: undefined reference to `XF86VidModeGetModeLine'

My box is a "slackware-current" with x11-6.9.0. I double checked opengl stuff and everything appears to be ok. Any idea about what's going wrong here?

Thanks in advance,
Enrico,
