paramsaver

hi
I'm trying to make "param saver" but I keep giving the following error:

Debug file information:
./parsaver.hal:1: execv (paramsaver): No such file or directory
./parsaver.hal:1: waitpid failed paramsaver paramsaver
./parsaver.hal:1: paramsaver exited without becoming ready

which is the right procedure to install the necessary files?
I put "paramsaver" and "paramsaver.c" under LinuxCNC / configs / my-mill.
regards
Alessandro

in a terminal :
alex@debian:~$ halcompile --install paramsaver.c

make KBUILD_EXTRA_SYMBOLS=/usr/realtime-3.4-9-rtai-686-pae/modules/linuxcnc/Module.symvers -C /usr/src/linux-headers-3.4-9-rtai-686-pae SUBDIRS=`pwd` CC=gcc V=0 modules
