In version 4, CholeskyDecomposition was accomplished by loading the package LinearAlegebra`Cholesky`.  In version 5, CholeskyDecomposition is built in and does not require loading a package. The message is simply trying to tell you this.

You can either ignore the message or you can edit the code by commenting out the line that has Needs["LinearAlgebra`Cholesky`"] in it.
