So you are telling libgd to use a font named arial;
it will add (.ttf) when looking for it.  So in order to satisfy this
request you need to have arial.ttf installed somewhere.

Well yes. If you want to use the Liberation fonts then say
   set term png font "LiberationSans-Regular"
or probably better, put it in an environmental variable.  E.g.
   setenv GNUPLOT_DEFAULT_GDFONT LiberationSans-Regular

Or if you think people are going to be requesting arial even though
you don't want to install it, how about
   cd /usr/share/fonts/liberation
   ln -s LiberationSans-Regular.ttf arial.ttf
