I often get the following error with the provided examples: ---- $ python2.5 changesymbol.py Exception in thread Thread-1: Traceback (most recent call last): File "/usr/local/lib/python2.5/threading.py", line 460, in __bootstrap self.run() File "/usr/ports/graphics/py-pyx/w-py-pyx-0.10/fake-macppc/usr/local/lib/python2.5/site-packages/pyx/text.py", line 639, in run read = self.pipe.readline() # read again IOError: [Errno 4] Interrupted system call /usr/local/lib/python2.5/site-packages/pyx/text.py:850: UserWarning: still waiting for tex after 5 (of 60) seconds... warnings.warn("still waiting for %s after %i (of %i) seconds..." % (self.mode, waited, self.waitfortex)) ... ---- It seems to finally work after several attempts (running the program 3 or 4 times). It is really annoying. I am almost sure it is due to some thread misuse. There is probably a race condition in the texrunner setup: delaying the threaded pipe reader loop by one second (arbitrarily) seems to make everything work fine. I have not investigated further. I think this should be fixed before the port makes it to the tree. Laurence, would you have a look a it? Otherwise I will do it but not before this WE at least. Eric.
