Hello Xavier,

I found the solution myself; putting a symlink from
/usr/local/share/doc/html to /usr/local/share/httrack/html
was the answer. I actually got it to work, though it crashed
after a couple of minutes the first time I was using it, and
took my whole system with it. But that may have had other
reasons, considering the plethora of nasty error messages
from the kernel I was getting on my console :-)

Regards

Frank
