[Rd] Possible R CMD check problem (PR#3070)

[ross at biostat.ucsf.edu]

Using R 1.7.0 I get 
* checking parcv-manual.tex ... ERROR
Could not create DVI version.

Although there is no apparent error.  The dvi file exists.
Possibly there is some problem with my TeX setup, but the following
messages don't suggest that either.

Here's the full log, which does show some documentation issues:
