I'm having a hard time fathoming your question, since "pterms" appears
nowhere in my source code to residuals.survreg.  Can we start at the
beginning, per the posting guide?

 1. What version of R are you running?
 2. What exactly are the statements you typed which give the message?

Note that residuals are not saved in a fit, but are computed later.
  fit <- survreg(Surv(time, status) ~ age + height, data=mydata)
  resid(fit, type='response')
