I tried to compile both:

httrack-3.30-RC-4.tar.gz 
and
httrack-3.23.tar.gz

Both failed with the following error message:

/bin/sh ../libtool --mode=link gcc  -g -O2   -o httrack 
httrack.o -lpthread -lhttrack
gcc -g -O2 -o httrack httrack.o  -lpthread -lhttrack
/usr/bin/ld: cannot find -lhttrack
collect2: ld returned 1 exit status
make[3]: *** [httrack] Error 1
make[3]: Leaving directory
`/Store/Programs/Internet/Browser/Off-Line

make[2]: *** [all-recursive] Error 1

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory

make: *** [all] Error 2

Can anybody help me with this problem?
