You probably forgot to say that you have also different versions of the 
package installed!

I get on all platforms:

 > drm(formula = response ~ conc, data = assay.data, fct = l4())
Error in drm(formula = response ~ conc, data = assay.data, fct = l4()) :
   Cluster not specified. Use e.g. y ~ x + cluster(id)


with recent versions of R and drm.


So time to update R and all your packages on all your platforms.

Best,
Uwe Ligges
