Invalid parameter provider

I have a puppet setup with +50 modules running but for some reason I can't get even the most vcsrepo example to work (from examples/clone.pp)
class gitrepo::config () {
vcsrepo

{ '/tmp/vcstest-git-clone': ensure => present, provider => git, source => 'git://github.com/bruce/rtex.git', }

}
results in
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Invalid parameter provider on Vcsrepo[/tmp/vcstest-git-clone] at /etc/puppet/environments/test/modules/gitrepo/manifests/config.pp:14 on node

if I try to remove the provider variable

vcsrepo

{ '/tmp/vcstest-git-bare': ensure => bare, provider => git, }

I get the following error:
Error: /Vcsrepo[/tmp/vcstest-git-clone]: Could not evaluate: vcsrepo resource must have a provider, available: bzr, cvs, git, hg, p4, svn

What am I doing wrong?
