cluster + tt terms in coxph

This is fixed in version 2.37-8 of the survival package, which has been
in my "send to CRAN real-soon-now" queue for 6 months.  Your note is a
prod to get it done.  I've been updating and adding vignettes.

I am receiving the following error when trying to include both tt
(time transforms) and frailty terms in coxph

coxph(Surv(time, status) ~ ph.ecog + tt(age)+cluster(sex), data=lung,

+      tt=function(x,t,...) pspline(x + t/365.25))
Error in residuals.coxph(fit2, type = "dfbeta", collapse = cluster,
weighted = TRUE) :
   Wrong length for 'collapse'

I tried both 64 bit (R.3.1.0) and 32 bit (R.3.1.2) in Windows 7 64bit
and get the same errors

Inclusion of tt and cluster terms worked fine in R2.9.2-2.15.1 under
Windows Vista 32 bit and Ubuntu 64 bit

Any ideas?
