I'm having problems installing it as well. If I run the shell script I get:
Usage: jave etc...
popopop.sh: line 2: session.jar: command not found
popopop.sh: line 2: xbean.jar: command not found
popopop.sh: line 2: jsr173_api.jar: command not found
popopop.sh: line 2: conf/properties: is a directory

and if I run it on the command line I get:
Usage: jave etc...
-bash: session.jar: command not found
-bash: xbean.jar: command not found
-bash: jsr173_api.jar: command not found
[1] 612
abyss:/Applications/PopopopPlayer noname$ -bash: conf/properties: is a directory

[1]+ Exit 126 conf/properties application.MainController
abyss:/Applications/PopopopPlayer

Any thoughts?
