    Hello !
    I'm afraid I'm a dummy Makefile.

 My goal in life is to politely ask you to run the configure script to actual-
 ly generate a real Makefile.
 Would you be kind enough to type "./configure --help" to see the options that
 will suit your needs ?   Please note that typing "./configure" without option
 will generate a Makefile that will suit most people needs.

 I wish you a good day. Please don't drive to fast.

root@server [/mpgtx]# ./configure
-bash: ./configure: Permission denied
root@server [/mpgtx]#
