Pre-compiled excutable

["narisara tanvirat" <nari_sara "-at-" hotmail.com>]

 Dear List
I have couple questions about installing AutoDock 3.0.5. I read the
 install
 instruction, but I dont quite understand how can I use a pre-compiled
 executable. In the instruction said
 To use a pre-compiled exectutable:
 ----------------------------------
Copy the executable for your hardware type and operating system to the
 desired place, usually where-ever you keep your other programs.
If you have problems running a pre-compiled binary, you may need to
 compile
 your own executable, for your specific machine architecture and
 operating
 system version.
I dont quite understand what the instruction means by "copy the
 excutable
 for your hardware type and OS to the desired place".
Anyhow, since I did not understand the first option so I tried the
 second
 option, which is to compile my own excutables:
 To compile your own executables:
 --------------------------------
(1) Change directory to dist_3.0/src, and all sub-directories, like
 autotors, autogrid, and autodock.
 (2) Read any README files.
(3) Edit the Makefile in each to be appropriate for your architecture.
 This
 may mean commenting and uncommenting various options.
 (4) Type "make" at the Unix prompt, in each sub-directory.
I tried but I could only compile one sub-directories which is
 protonate. I
 believed my problem was that my workstation didnt have gcc so I
 downloaded

 so I got the error massage "gcc doesnt install".
I would like to know if any of you know how to install gcc. By the
 way, my
 workstation is HP9000.
