That definitely won't compile :)
You should be able to just declare the exec and package(s) resources
separately and define a relationship, like:
exec { "Installing nginx via passenger":
path => "/bin:/usr/bin",
environment => "HOME=/root",
command => "passenger-install-nginx-module --auto-download --auto",
user => "root",
group => "root",
unless => "ls -l /opt | grep nginx",
logoutput => on_failure,
require => Package[$prerequisites],
}
That last line should work for you. Otherwise you could define it the
opposite way around:
package { $prerequisites:
ensure => installed,
before => Exec["Installing nginx via passenger"],
}
Both those methods should work, but I have a vague memory of the first
method failing in a point release or two.
What version of Puppet are you running? You may have a much clearer
way of expressing the conditional you're using than the somewhat messy
case statement you're using at the moment.
