Rtools questions

Hello:


       1.  How can I tell when the development version of Rtools has 
changed?  For the past few years, I've installed the development version 
of R tools with each new release of R.  I encountered problems with this 
a few days ago, so I rolled back to Rtools212.exe.  Unfortunately, I 
seem to have more problems with that version.  My latest install was 
under Windows 7 Home Edition.  My previous problems were on Vista, but I 
also have access to Fedora 13 Linux.


       2.  "R CMD check" ends with the following:


* checking examples ... OK
* checking PDF version of manual ... WARNING
LaTeX errors when creating PDF version.
This typically indicates Rd problems.
* checking PDF version of manual without hyperrefs or index ... ERROR
Re-running with no redirection of stdout/stderr.
Hmm ... looks like a package
Error in texi2dvi("Rd2.tex", pdf = (out_ext == "pdf"), quiet = FALSE,  :
   unable to run 'pdflatex' on 'Rd2.tex'
Error in running tools::texi2dvi
You may want to clean up by 'rm -rf 
C:/Users/sgraves/AppData/Local/Temp/Rtmpr6z3
r6/Rd2pdf55b96c9a'


       This is using Rtools213, downloaded April 4 from 
"www.murdoch-sutherland.com/Rtools" with R installed as follows:
