This is the easiest way to install glest in linux!
Version 3.2.2 ( linux 32bit with official binary!):
http://liflg.org/?catid=7&gameid=87( I would suggest to run the installer as normal user and install glest in the users home directory!
Now test it. If glest works for you, edit the file glest.ini and set some better looking screen settings ( 10280x1024 or whatever...) ! )
!!!! If there are any problems with these installers, please report them here too !!!!! (HINT: !! If the game works modify file glest.ini to setup a better display resolution! !!)
