Code:
bash-3.1$ ls -lh /usr/local/share/tessdata/eng.unicharset
-rw-r--r-- 1 dec users 0 2010-04-05 19:53 /usr/local/share/tessdata/eng.unicharset
If you look closely you'll see that the "existing file" is a measly
0 bytes long. You'll need to separately download that file and place
it into /usr/local/share/tessdata/ instead of the placeholder.
Cheers,
