Depending on the definition of "similar",
I think you get some of it in package  
mclust

AFAIRemember, the R and S+ versions of mclust have some differences, I
think mostly because Insightful had changed (improved?) the original
Fraley/Raftery code.

Note that Venables and Ripley MASS (p.262-6) also have a somewhat extended
example of (normal) mixture fitting.
