Several users asked me if HTTrack would compile on OSX 
system. I really don't have any idea, as I can't 
access any machine with OSX installed - but the 
sources compile on most (Windows, Unix, Linux..) 
systems, and maybe also on OSX.
Therefore, if you can do that, please send me 
(roche@httrack.com) any feedback, the configure script 
might be modified to fit OSX specific options.

Thanks!
