How do I set the path

Very new to this type of thing so go easy on me.......

I have downloaded a command language for data display.
It came as ncl_ncarg-5.2.1.MacOS_10.6_i386_64bit_gcc421.tar.gz and I unzipped/tarred it into my local directory.
The new directory, ncl_ncarg-5.2.1.MacOS_10.6_i386_64bit_gcc421, contained three sub directories, bin, include and lib. The bin directory seems to contain the executables.
One of the executables is the command ncl, to use this (according to website where I got it) is simply,
ncl filename.ncl
I have a suitable file on my desktop and cd to the desktop but just get a command not found error when I try. I think this is something to do with the path, but am not sure how to set it or what to set it to.
Any help greatly appreciated.......Smilie

chroot(1M)						  System Administration Commands						chroot(1M)

NAME
chroot - change root directory for a command SYNOPSIS
/usr/sbin/chroot newroot command DESCRIPTION
The chroot utility causes command to be executed relative to newroot. The meaning of any initial slashes (/) in the path names is changed to newroot for command and any of its child processes. Upon execution, the initial working directory is newroot. Notice that redirecting the output of command to a file, chroot newroot command >x will create the file x relative to the original root of command, not the new one. The new root path name is always relative to the current root. Even if a chroot is currently in effect, the newroot argument is relative to the current root of the running process. This command can be run only by the super-user. RETURN VALUES
The exit status of chroot is the return value of command. EXAMPLES
Example 1 Using the chroot Utility The chroot utility provides an easy way to extract tar files (see tar(1)) written with absolute filenames to a different location. It is necessary to copy the shared libraries used by tar (see ldd(1)) to the newroot filesystem. example# mkdir /tmp/lib; cd /lib example# cp ld.so.1 libc.so.1 libcmd.so.1 libdl.so.1 libsec.so.1 /tmp/lib example# cp /usr/bin/tar /tmp example# dd if=/dev/rmt/0 | chroot /tmp tar xvf - ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
cd(1), tar(1), chroot(2), ttyname(3C), attributes(5) NOTES
Exercise extreme caution when referencing device files in the new root file system. References by routines such as ttyname(3C) to stdin, stdout, and stderr will find that the device associated with the file descriptor is unknown after chroot is run. SunOS 5.11 15 Dec 2003 chroot(1M)
