please guide thr' correct steps to compile source code...

dear all,
i downloaded entire set (7 files) of XFree86 4.5.0 source code in the
form of .tgz files. after untaring them under xc and creating a
shadow directory named build i tried following commands under build:

$ make World > World.log
$ make install
$ make
completing till here i got X11 under /etc and X11R6 under /opt.
during compilation error messages came, but surprisingly compilation
continued till end.
i tried from binary file xf86-4301-qnx6-bin.tar.gz earlier and server
was up. this time content in X11 & in X11R6 are not the same as i
got from binary image.
please guide me if any changes are required in the process. i want to
generate a similar kind of binary file from the source codes.

thanks & regards,
