Damn it. Again some libtool madness :(

Yes, perfectly.. but the build process is a bit complicated.

Can you try to install up-to-date gcc, libtool, automake, 
autoconf and so on ?
I use for 'emegency cases' this commandline:

libtoolize --copy --force \
        && aclocal -I /temp/httrack-*/m4 \
        && automake --add-missing --copy --force-missing \
        && autoheader \
        && autoconf \
        && echo "success"

I use:
- libtoil 1.4.2a
- automake 1.7
- autoconf 2.59

But more recent release may solve your problems
