Thanks.
I installed tesseract with configure, make, make install, then tried to run it
but got the following error message:

 Unable to load unicharset file /usr/local/share/tessdata/eng.unicharset

.  In the README file there is:

Non-Windows:
You have to tell Tesseract through a standard unix mechanism where to find
its data directory. You must either:
./configure
make
make install
to move the data files to the standard place, or:
export TESSDATA_PREFIX="directory in which your tessdata resides/"
(or equivalent) in your .profile or whatever or setenv to set the environment
variable. Note that the directory must end in a /
HAVING tesseract and tessdata IN THE SAME DIRECTORY DOES NOT WORK ANY MORE.


.  I tried with `export TESSDATA_PREFIX="/usr/local/share/tessdata/"', but
nothing.  Now I'm stuck.  Any suggestion please?
