R help - Nov 2011 - Bootstrap values for hierarchical tree based on distaance matrix

I would like to get an hierarchical clustering tree with bootstrap values
indicated on the nodes, as in pvclust. The problem is that I have only
distance matrix instead of the raw data, required for pvclust. Is there a
way to get it?

fit1 <- hclust(dist) # an object of class '"dist"
plot(fit1) # dendogram without p values

library(pvclust)
fit2 <- pvclust(raw.data, method.hclust="ward",
   method.dist="euclidean")
plot(fit2) # dendogram with p values
