System: Linux morr-slack 2.6.18.8-smp #2 SMP Fri Mar 16 19:50:11 CDT 2007 i686 
pentium3 i386 GNU/Linux
Architecture: i686

Installed:
Mesa-6.4.2          Graphics library meta package, similar to SGI's OpenGL
MesaLib-6.4.2nb3    Graphics library similar to SGI's OpenGL
It's slackware-current.

>Description:
        graphics/gle cannot be installed. configure fails with error:
checking for IceConnectionNumber in -lICE... yes
checking for glGetError in -lGL... no
configure: error: Cannot find required GL library
*** Error code 1

and config.log:

>How-To-Repeat:
        build graphics/gle on linux
>Fix:
        Adding LDFLAGS+= -lpthread works around that problem, but I don't think 
it's correct thing.
