Can't compile old version of sasc-ng

Hi All,

I am trying to compile the program sasc-ng in order to decode encrypted DVB-T (digitenne). I am trying to follow the following manual:
http://www.cccamforum.com/forums/showthread.php?t=67988

I am told an here an old version of sasc-ng works without any problems:
http://www.sat4all.com/forums/ubbthread … /1992597/4 (dutch link)

So here we go:

cedric@laptop:~/tmp$ mkdir sasc-ng
cedric@laptop:~/tmp$ cd sasc-ng/
cedric@laptop:~/tmp/sasc-ng$ hg clone --rev 28d5438fad67 http://85.17.209.13:6100/sc
destination directory: sc

cedric@laptop:~/tmp/sasc-ng$ cd sc/contrib/sasc-ng/
cedric@laptop:~/tmp/sasc-ng/sc/contrib/sasc-ng$ chmod +x configure makelinks.sh dvbloopback/module/config_dvb.pl

Add #include <sys/stat.h> to plugin_scan.c

 
cedric@laptop:~/tmp/sasc-ng/sc/contrib/sasc-ng$ nano dvblb_plugins/plugin_scan.c

Now try to compile

cedric@laptop:~/tmp/sasc-ng/sc/contrib/sasc-ng$ make clean
