[Mjpeg-users] libquicktime

[E.Chalaron]

Gday

For those who are not aware, my favourite hobby is to crash my linux box and therefore to compile mjpeg tools every so often...
today it is not mjpeg tools it is libquicktime :
make gives me :
libtool: link: cannot find the library `/usr/X11R6/lib/libGL.la'

what should provide this file ?
Thanks
ECh.
