[R] changes in glm?

[G.Janacek]

I am running some simulations which involve fitting a glm with 
Binomial error ( in fact Bernoulli) and logistic link. Running R 0.63 
I have no problems. However I need more speed so migrated to our UNIX 
boxes which run
Version 0.90.1  (December 15, 1999)

Here I get an error


Error in (if (is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y 
= Y,  : y must be univariate unless binomial


which has baffled me.
So I as your indulgence and ask

(1) What if anything has changed in glm from 0.63 to 0.90?
(2) Is glm sensative to changes of word length?
(3) Given making R on an Alpha is beyond me (so is a problem) should 
I migrate to a later version of R or does this bring more problems in 
its wake?
(4) Does anyone recognise the error and if so I would appreciate some 
info. I'm sure it is my stupidity but ..

Sorry to trouble you
