The problem is, that busybox searches for MD5 sum using file's full path,
including leading slash

    6583a05c20dfb3784cd48fef2c59aa05  /etc/protocols

whereas in md5sums leading slash is omitted

    6583a05c20dfb3784cd48fef2c59aa05  etc/protocols

On my Debian box md5sums files has no leading slashes, so the quickest fix is
to replace

    sprintf(bin2hex(md5line, buf, 16), "  %s", name_ptr);

with

    sprintf(bin2hex(md5line, buf, 16), "  %s", name_ptr + 1);

in archival/dpkg.c:1553. Another option is to look for both.
