[R-sig-ME] post hoc tests for aov with mulitple error terms?

Dear All,

I am conducting an anova with multiple error terms:

model<-aov(time~treat+Error(site/treat))

and would like to be able to do post hoc tests (eg Tukeys) but the aov 
function only allows Tukeys test with aov.objects and the aov with multiple 
error terms creates and aov.list.

Can anyone suggest a solution to this?

previous posts on the forum have stated that I can use the following code 
with the glht function, but this also only works on aov. objects.

summary(glht(model, linfct=mcp(V="Tukey")))

Any ideas would be very much appreciated!!

Emma
