That package has been archived (http://cran.r-project.org/src/contrib/Archive/surv2sample/).
Only a source .tar.gz is available.

AFAICS it needs to be modified to work with R >= 3.0.0.
As it is now it can't be installed and doesn't pass R CMD check.
It needs to be fixed.
You could try to contact the original author.
