Non parametric clustering

Hello,

I need to run an unsupervised clustering analysis on several non normal
variables.
I think that mean shift algorithm fit perfectly my needs.
Is there a package that run this kind of analysis?

Is there any other non parametric cluster analysis that you would suggest me?

Thank you in advance
