can you library(MASS) with R 1.9.0?

Thank you!

I had not used tools/rsync-recommended -- I just coped the rsync command 
from the R FAQ (i.e., rsync -rC --delete rsync.R-project.org::r-devel R).

The tools/rsync-recommended command downloaded the various recommended 
packages.

However, to get this I had to get the latest version of the tools (out of 
<http://www.stats.ox.ac.uk/pub/Rtools/tools.zip>http://www.stats.ox.ac.uk/pub/Rtools/tools.zip), 
and after changing my path to use it I get the dreaded "You have multiple 
copies of cygwin1.dll on your system" error, even though I have set my path 
so that I have only one copy of cygwin1.dll in my path (as far as I can see):

$ type -a cygwin1.dll
cygwin1.dll is /cygdrive/c/R/tools/cygwin1.dll
$ ls
c:\R\tools\ls.exe: *** fhandler size version mismatch detected - 0x70/0x6C.
You have multiple copies of cygwin1.dll on your system.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version.  The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution.

# this is the path I'm had for the commands above -- this command run with 
a different PATH so that it can run
$ echo $RPATH | tr ':' '\012'

(I'm running under Windows 2000).

Any suggestions on how to get things working again are much appreciated.
