perl DBI help

Hi,
for my perl file to be executed I need to install DBI,
DBD:ODBC. I have tried install by ppm. But my college server does not
allow me to do that. How can I download and install individual
packages. I have some DBI.zip which has DBI.ppd, read me file. If I try
to install that .ppd file it is saying "no suitable installation target
found for package DBI". Shall I need DBI.pm file? Can u please give
idea of what to download, where to put that file, how to install it? I
am haing my perl filder in C:\ drive. I am using WInXP, Active state
perl 5.8.X..

Thanks & regards,
Siva Rajesh
