#1 Won't configure -- libGL

[Stevan White]

This is Mandrake 10
rtprof 0.5.1

./configure gives
checking for glBegin in -lGL... no
configure: error: Missing libGL.

However, libGL is definately present in /usr/X11R6/lib

Tried setting LD_LIBRARY_PATH to include this. No dice.

Mandrake comes with two versions of autoconf (2.5 and
2.1.2), so I tried forcing the older version. No dice.
