[BioC] clusterStab using a correlation distance

I am interested in using the package clusterStab and in particular the
clusterComp function as a way to test the stability of the clustering of
the dendrograms I have produced from microarray data.  The problem I
have is that I would like to use a correlation distance (1-cor()) and it
appears that the only option is to use a Euclidean distance.  Is that

Is there a way to alter the input data so that a Euclidean distance is
in effect a correlation distance?

If not would is be easy to change the source of the function?

Many Thanks
