I am in the process of converting an old-ish LR-grammar to work with ANTLRs 
LL-principles which is an interesting, but educational, journey.

I'm running on MacOSX and looking at my single remaining non-LL(*) decision and 
was hoping to get some help from the DFA. unfortunatley displaying it does not 
work. When asked to produce the DFA, GraphViz pops up a message like 
"DOTxxxx.out could not be opened. GraphViz cannot open this kind of file." The 
message is then repeated for the ".in"-file.

ANTLRWorks preferences seems to be pointing in the right direction, as some 
other graphs are produced alright. (Although I do not know if ANTLRWorks uses 
GraphViz for that...)

I'm using latest ANTLRWorks (bundled, but has also tried the jar), and have 
latest GraphViz (2.20.3 from 2008) for MacOSX.

Anyone have any clue, or hint on what to try?
