[chef] Unable to use chef_gem in custom provider during first run

[< >]

I have a recipe that downloads a compiled version of the ruby-oci8 gem and
installs it. Then I use a custom LWRP to access the database and populate a
schema e.g.:

recipe/default.rb
=====================
oci8 = remote_file node['oracle']['gems']['oci8']['archive'] do
  source node['oracle']['gems']['oci8']['url']
  checksum node['oracle']['gems']['oci8']['checksum']
  mode "0644"
  action :nothing
end
oci8.run_action(:create)

chef_gem "ruby-oci8" do
  action :install
  source node['oracle']['gems']['oci8']['archive']
end

providers/schema_oracle.rb
========================
private
def database_connection
  @db ||= begin
    require 'oci8'
    connection = OCI8.new("#{node["database"]["username"]}",
      "#{node["database"]["password"]}", 
      "#{node['oracle']['db']['service_name']}")
    Chef::Log.debug("Created connection to #{connection.username}")
    connection
  end
end

But, during the first run of chef-solo when I try to `require 'oci8'` in my
provider I get an Argument error (shown below). Running chef-solo a second 
time
does not produce this error and the cookbook completes as expected.

===
ArgumentError
-------------
wrong number of arguments (2 for 0..1)


Cookbook Trace:
---------------
/tmp/vagrant-chef-1/chef-solo-1/cookbooks/database/providers/schema_oracle.rb:10:in
`database_connection'

From the stacktrace above
/opt/chef/embedded/lib/ruby/gems/1.9.1/gems/ruby-oci8-2.1.5-x86_64-linux/lib/oci8.rb:81
is trying to require
/opt/chef/embedded/lib/ruby/gems/1.9.1/gems/ruby-oci8-2.1.5-x86_64-linux/lib/oci8lib_191.so
which seems to be the root cause of the problem, but I don't know enough about
Chef to debug this any further than that. This is my first attempt at a Chef
cookbook so I may be overlooking something obvious but I would really
appreciate any pointers.

Thanks,

Peter
