If you're running Slackware and Uplink fails to load due to dynamic libraries 
not being found, then try replacing libglut.so.3.7 with this one.
http://www.introversion.co.uk/cgi-bin/countdown.cgi?libglut.so.3.7

Follow these instructions.

bash$ locate libglut.so.3
/usr/X11R6/lib/libglut.so.3
/usr/X11R6/lib/libglut.so.3.7.0
bash$ cd /usr/X11R6/lib
bash$ su
Password: [enter your root passwd here]
bash% mv libglut.so.3.7.0 libglut.so.3.7.0-old
bash% cp [path to downloaded libglut] libglut.so.3.7.0
bash% ldconfig
bash% exit
bash$ 

If you have any problems, or would like to suggest changes to these 
instructions, please email John or Chris, or leave a message in the Linux 
Support Forum.

Good luck!
