This is usually installed by default -- within Apache.
Does it not show in: Cpanel & Installed Modules?
Or if you have shell access, type in:
# man lwp-request
If any instructions show up, it is installed.
Of course, you can always just &install and run& the script, any script actually, to see if required modules are installed -- if so it will work and no problems.
Gotta like that!
