I don't have single quick-n-easy install script.
But the pieces are here, and the steps are

(1) Copy VTM.pm into one of your perl @INC folders.
    To find out where those libraries are, type
    
      $ perl -e 'print join("\n",@INC)'
      /usr/local/lib/site_perl
      ...

    which should print out a bunch of folders.
    On cs, I put it in /usr/local/lib/site_perl

(2) Edit the first line vtm_perl so that it points
    to the location of your perl program.
    To find out where that is, type

      $ whereis perl
      /usr/bin/perl

    so on cs, the first line of vtm_perl is 

      #!/usr/bin/perl

(3) Copy vtm_perl /usr/local/bin or somewhere similar
    where it will be easily found.

(4) Edit vtm.c to point to the full path of vtm_perl
    as you set it in (3).

(5) Compile vtm.c :

     $ gcc vtm.c -o vtm

(6) Finally, copy the vtm executable to /usr/local/bin

     $ sudo cp vtm /usr/local/bin/vtm

If all of that is set up, then you should see

     $ whereis vtm
     /usr/local/bin/vtm
     $ vtm -h
     Usage: vtm [programfile] [switches]
     ...
