It doesn't work on my machine (Darwin 7.8.0/Mac OS 10.3.8)
right away.

I got linker errors on 3.33 and 3.32 (have not tried other
versions), and was able to fix them on 3.32 by setting my
CFLAGS to "-g0 -O0" (that's dash gee zero dash oh zero),
neither compiled with my usual "-fast -mcpu=7450", nor did
they compile with no CFLAGS at all. The -O0 will make
httrack use a bit more cpu, but it actually compiles and links.

For the tutorial/instruction lovers:

export CFLAGS="-g0 -O0";
./configure;
make;

(and then..)
sudo make install;
httrack;
(or)
cd src;
./httrack
