Jussi, Unfortunately, just copying the binary and the libs it requires under /host_usr didn't work. When I tried to run it inside Scratchbox, the default dynamic loader in /scratchbox/host_shared/lib was used to load the libs, and that produced a bunch of libc version incompatibility errors.
The only way I could make my binary to run inside Scratchbox was to copy the host dynamic loader (from /lib outside Scratchbox) under /host_usr, and make a couple of minor changes in sb_alien.c and libsb.c so that it would be used instead of default loader when my binary is run. I was a bit surprised to find the default loader (/scratchbox/host_shared/lib/ld.so) hardcoded in sb_alien and libsb and no way for the user to configure it. Wouldn't you say it makes sense to provide the user with a means to control which loader should be used, exactly for the purpose of running alien tools inside Scratchbox?
