Hello karthik167, and welcome to the Monastery!

Say your perl scripts reside in the directory /foo/bar/scripts. Create a new directory, for example /foo/bar/scripts/inc, and simply copy the additional module (.pm file) into it, along with any dependencies not already installed on the target nodes. Then add the following to the head of each script:

use lib '/foo/bar/scripts/inc';
[download]

and use the additional module in the normal way. (See lib.) This should provide an acceptable workaround.

Hope that helps,
