Works for me:
kbarber:~ ken$ cat template.erb
$restricted <%= fqdn %>
$ideal_load <%= num_cpu.to_i + 0.5 %>
$max_load <%= num_cpu.to_i * 1.2 %>
kbarber:~ ken$ cat template.pp
$num_cpu = 5
notice(template("/Users/ken/template.erb"))
kbarber:~ ken$ puppet apply -v template.pp
notice: Scope(Class[main]): $restricted kbarber.lan
$ideal_load 5.5
$max_load 6.0
info: Applying configuration version '1308143319'
notice: Finished catalog run in 0.01 seconds
kbarber:~ ken$
Can you copy my example exactly and see what happens?
Otherwise sounds like a versioning thing - what version of puppet/ruby
are you running?
ken.
