Yes. I know that this is in the source code. But it is not in the Mac  
binary. That is, apparently it does not get built for Mac. I have not  
built this myself from source, however. Perhaps it gets built under  
some circumstances and not under others on Mac

Right. I realize that to get wxPython, you also need wxWidgets on  
Linux. On the Mac, this is not a separate install. However, I'm not  
sure, but I think that wxWidgets comes packaged with the wxPython  
binaries for Mac. I have a folder /Library/Frameworks/.../wxpython  
that holds the wxPython stuff and another /Library/Frameworks/.../wx  
that I *think* is wxWidgets stuff. But none of them have wx-config.

Looks like there are only wxWidgets binaries for Debian and Ubuntu.  
None for Mac or other platforms (maybe a special installer for Windows).

I'm trying to see if there is some way to compile vdigit for the Mac  
without having to compile the entire wxWidgets package (or wxPython)  
from source. Among other things, I'm worried what this might do to my  
existing wxPython (and I think wxWidgets) installation. This is why  
it is important to find out exactly which files vdigit actually needs  
in order to compile. Maybe I (and all other people with Mac installs)  
already have those files. If not, the next question is do we need to  
compile something from source to get them (I hope not), or can we  
just grab them from source (e.g., *.h header files)?
