I tried to proceed as described on http://pharo-project.org/community/issue-tracking and tried to search in the mailing list in the archive. But in trying to access the archive I get the message from Nabble(?): This node has been deleted Here a problem description: I installed Pharo latest version on debian lenny 64 bit and it works properly from start on, but I had/have some problems with Squeak. I installed Pharo (same procedure as above) on red hat 64 bit Kernel 2.6.34.7-61.fc13.x86_64, AMD Turion 64 X2 Mobile Technology TL-56 and it does not work, but Squeak works properly. The message is: [bb@localhost Pharo-1.1-OneClick.app]$ ./pharo.sh libGLU.so.1: cannot open shared object file: No such file or directory could not find module vm-display-X11 Abgebrochen (Speicherabzug geschrieben) [bb@localhost Pharo-1.1-OneClick.app] I installed repeatedly and tried to use available VM's from Squeak and also tried some other "tricks", i.e copy all Pharo-files in the same directory ... May be someone else has some experience with Pharon on red hat? Please tell me if it is worth to make a ticket? Regards BB
