This is really strange, and I have not been able to reproduce this on  
OS X or Linux.

One issue to watch out for is that the PATH setting texworks sees may  
not be the same as the PATH you see in a terminal window -- at least  
on OS X and Linux, this depends how texworks is launched and how the  
PATH for shell windows is configured. On OS X, for example, texworks  
three different environments depending whether it is launched from the  
Xcode IDE (during development), from the Finder (the usual end-user  
scenario), or from a Terminal command line. Only in the last of these  
cases does it inherit the same PATH as my usual bash shell.

I have just modified the processing of binpaths in  
TeXDocument::typeset(), and in particular I have enhanced the error  
message if the tool is not found so that it now lists the paths that  
were actually searched. So this way you'll more easily be able to see  
where it is really looking, once the defaults or Preference settings  
are taken into account, together with the current PATH. Maybe this  
will help clarify what's going on.
