You just use the following method to set the variable.  The first command sets 
it and the second makes it an environment variable (setenv combines these 
into one step).

PKG_PATH=ftp:// ...
export PKG_PATH

If you're really interested in knowing what the differences are between the 
shells, there are many good sources out there.  A good phrase to look up 
is "bourne shell", if you prefer bash.  You may also want to look into the 
csh to understand what it does differently.
