Smokeping is looking for a Perl module called LWP::UserAgent.pm and it
isn't in any of the places that it's been told to look.  The places it
looks are listed in a Perl array called @INC which is just a list of
paths, like the environment variables PATH (which is used to search
for executables) or MANPATH (for 'man' pages).  The documentation for
Smokeping shows how to add paths to @INC with the 'use lib' statement.

The list above is the contents of @INC, which is where Smokeping looks.

This is the place where the module was requested (hopefully - there
can sometimes be problems with Perl line numbering if you're using
things like speedy-backend).  Since you're not developing the code,
you don't really care what the line number is anyway.

This is the chain of statements which resulted in the failing call.

..ooOoo..

Now all you have to do is make sure that your LWP::UserAgent is in one
of these places.  If you don't have LWP::UserAgent then take a trip to
CPAN and get it.  If you do have it, but it is not in one of the
places listed in @INC, then you can add that directory as explained in
the Smokeping documentation.  Look at the file /usr/local/bin/smokeping
using any text editor.  If you type

perldoc /usr/local/bin/smokeping

or

man smokeping

you will see the documentation that you need.
