Linux - instalacion del amsn

buenas, aver si alguien me puede ayudar, he innstalado red hat 9 y estoy intentando instalar el amsn, lo he bajado de http://amsn.sourceforge.net, en esa pagina me dice que lo descomprima luego ./amsn en la carpeta donde lo descomprimi, hago eso pero me sale este error

./amsn: line 64: syntax error near unexpected token `}'
./amsn: line 64: `} else {'

otra forma es wish amsn pero me sale esto

Pues parece errores en el codigo, fijate en la pagina si esa es la version "stable" o si ha salido algun bug
