Powershell command for adding the package

Dear All, 

Am using SCCM 2007 and Powershell v1.0. First thing I would like to ask is does the version of powershell and sccm are interdependent? Why beacuse, am searching for the cmdlet to add the package to the distribution point. Still I didn't get the command to add. All the commands that I got are used in sccm2012 and powershell v3.0. When I use any of the commands, am getting "System.String() does not contain this method" as the error. I searched in Powershell prompt to get the list of cmdlets used. I did not find any relative command to add the package to the dp. 

Please help.
