Can't locate LWP/UserAgent.pm in @INC

If you're trying to run some perl related script, but get this error

Can't locate LWP/UserAgent.pm in @INC ...

then you'll need to install libwww-perl.  To do that, type:

wget
tar xvzf libwww-perl-5.837.tar.gz
cd libwww-perl-5.837
perl Makefile.PL
make
make install

Another possible solution:

perl -MCPAN -e 'install Bundle::LWP'
