if you write
<% if val != "<%= hostname %>" %>
The thing between <% and %> will be interpreted as ruby code but you mix
in erb syntax inside this ruby fragment. Maybe erb thinks the ruby code
ends after the inner %> not after the outer %>. However what you really
wanted to write was probably
<% if val != @hostname %>
Notice that I am addressing hostname as an instance variable. Addressing
it as plain hostname (as a function) does also work but should be avoided
because you may accidentally call a real ruby function instead
(http://projects.puppetlabs.com/issues/14527 is a great example for
that)
So the endresult could be
<% hosts.each do |val| -%>
<% if val != @hostname -%>
host (<%= val %>)
<% end -%>
<% end -%>
