Fibonacci, yes, I'll add it to the SF bug tracker, but I'm unable to login on SF to post, will probably be fixed soon and I'll do it..
about not being to launch it without install, it's normal, you need two things :
1 - compile amsn against tcl/tk 8.5, I suggest you copy over your amsn to a new dir called amsn-8.5/ and then do
./configure --with-tcl=/path/to/tcl/8.5/unix/dir --with-tk=/path/to/tk/8.5/unix/dir
2 - launch/install wish 8.5. If you don't want to install, do this :
make shell SCRIPT=/absolute/path/to/amsn-8.5/amsn
It will modify your environment locally (not affecting your bash environment, only the 'make' process environment) so that wish8.5 can be launched without being installed.
