[ALPS-users] vispython not found in recently installed alps-2.3 in Ubuntu !

Dear alps users, After struggling I just installed alps-2.3 in Ubuntu . I build the alps-2.3 successfully. Now i was trying to do some tutorials in the directory ./alps-2.3.0-src-with-boost/alps/tutorials by runing the executable ./runtutorial.sh which fails saying /runtutorial.sh: 10: ./runtutorial.sh: vispython: not found ./runtutorial.sh: 10: ./runtutorial.sh: vispython: not found What should I do. Is there anything else needed to install to install alps successfully and use it for application. Please tell me to solution to use alps without error. Thanks, Santu
