[Rd] make check failures (PR#2884)

[ross at biostat.ucsf.edu]

R Version 1.7.0 Patched (2003-04-28), built on Solaris 2.8
with gcc 3.0.3.
Obtained via rsync -rC rsync.r-project.org::r-patched R

I'm not sure how signficant these difference are during development,
but after an apparently successful build I got the following
discrepancies in make check:

Note that configure reported
checking for recommended packages... ./src/library/Recommended/survival_*.tar.gz not found

I don't know what the deal is with the survival library.
