Try using psurvreg(x, mean=fit2$coef, scale=fit2$scale, dist='extreme')
The psurvreg and qsurvreg functions inherit the same parameterizations
as survreg. I have trouble myself matching the location/scale form of
survreg to default parameterizations used in the weibull, extreme, etc
distributions

Before being helpful let me raise a couple of questions:
1. "I know I'm looking at longevity data (which is believed to have a
Gompertz distribution for mammals dying from 'old age')".
I'm not as convinced. The Gompertz is a nice story, but is

Dear list:
I am attempting to use what I thought would be a pretty straightforward
practical application of Cox regression. I figure users of the survival package
must have come across this problem before, so I would like to ask you how you
dealt with it. I have set up an illustrative example a
