Added missing packages.

[rmestrum]

On a minimum install CentOS 7 system the gcc and ruby-devel packages are not installed.

When installing the puppet-forge-server gem the installation fails with the following errors:

Initially the error is:

[root@localhost ~]# cd /etc/puppet/manifests/
[root@localhost manifests]# puppet apply --parser future site.pp
Notice: Compiled catalog for localhost in environment production in 1.15 seconds
Error: Execution of '/usr/bin/gem install --no-rdoc --no-ri puppet-forge-server' returned 1: Building native extensions.  This could take a while...

This error can be solved by installing the ruby-devel package.

Then the installation fails with

[root@localhost manifests]# puppet apply --parser future site.pp
Notice: Compiled catalog for localhost in environment production in 1.13 seconds
Error: Execution of '/usr/bin/gem install --no-rdoc --no-ri puppet-forge-server' returned 1: Building native extensions.  This could take a while...

After installing the missing packages the installation finshes successfully
