It only is configured to build under MSVC++6 for Windows.
It only accepts uncompressed bitonal tiffs.
It's command-line only. No GUI.
It performed abysmally on the provided testimage.tif
But it did build. :)

Also in that directory you mentioned, there is a utility called ocrspell, 
which is crufty code that I can't get to configure properly on a modern linux 
system ... to give you an idea, it is hardcoded for ispell 3.1.08 and it's 
dependent files, and most systems are using aspell 0.50.x or 0.60.x. (ispell 
3.1.20 or higher) The (other) problem here is that the dictionaries are very 
different from what the program expects.

Granted, this was a fairly quick look, but I don't see this as being useful 
very soon without a lot of gnashing of teeth.
