Experimental Solaris 11 IPS packages for Puppet 3.0.0-rc7, Facter 1.6.12 and Hiera 1.0.0 are available under

http://downloads.puppetlabs.com/solaris

They are:

puppet@3.0.0,5.11-9211.p5p 
facter@1.6.12,5.11-819.p5p 
hiera@1.0.0,5.11-116.p5p

The versioning scheme for Solaris is different from the default scheme. The versioning scheme is

<product>@<product-version>,<consolidation>-<build number> .

Specifically the RC candidates and the Final version are distinguished only by their build number which is monotonic.

To install these packages, download them from the above link and use IPS pkg command. E.g for puppet

pkg install -g ./puppet@3.0.0,5.11-9211.p5p puppet

Note that since this is experimental and each product is in its own repository archive, Hiera and Factor need to be installed first before Puppet is installed.
