Ptolemy 0.7 beta is out. I've tested it on FreeBSD during alpha phase. Anyone interested in trying out the beta can get it at ptolemy.berkeley.edu. What is ptolemy? It is big. The best place to look is the web page. It is a graphical rapid prototyping programming environment with various models of computation. I use it for schematic representation of specifications for control systems that also happen to run. It is a combination of old technology and good new technology, with [incr tcl] based tycho slowly replacing some of the older stuff. It may not be a port, but I've put my build script at freebsd.org in ~ftp/pub/dufault/ptolemy.build. There are a few known bugs: 1. vem has a memory leak and will eventually become monstrously large. Save frequently and restart occasionally. 2. phkmalloc will detect a free block being freed when pigi exits in the shared library version of the program, and rarely the same error at other times. I've sent out the trace back and hopefully a fix is forthcoming. 3. Xtk complains when you click "ok" on some of the old Athena widgets and prompts with a "should I continue" sort of question, stopping the program waiting for keyboard input. This problem existed in Linux and evidently cleared up in newer versions of XFree86 according to the Linux testers. I just start up pigi with "yes | pigi" for now.
