R 1.9.1 package installation problems

Hello,

I am writing as an administrator, not as an R user, so forgive me if I
am not completely knowledgeable about R.

I have a user who is creating an R package for windows from a Linux
environment using the crossbuild environment by Jun Yan and A.J.
Rossini. The packages she generated worked fine until she tried to
install in R 1.9.1 for Windows. Now when she installs with

   install.packages( "Zelig", CRAN="http://gking.harvard.edu" )

it results in two errors.

First, it claims there are some missing files. When I look in the zip
file, the files are there, but they coexist with other files that have
the same name differing only in case. So there is both 'help/zelig'
and 'help/Zelig', and this is causing R to think that one of them is
missing.

Yes, Windows will do that sort of thing to you. This stems from
the Zelig sources themselves, 

[pd at titmouse tmp]$ tar tvfz ~/Zelig_1.1-2.tar.gz | grep -i /zelig.Rd
-rw-r--r-- king/king      2905 2004-04-17 02:53:49 Zelig/man/Zelig.Rd
-rw-r--r-- king/king      2779 2004-06-18 23:13:21 Zelig/man/zelig.Rd

but pretty obviously, that's a bad idea.... Incidentally, "R CMD
check" finds multiple problems with the package, but filenames
differing only in case is not among them, so it looks like the checker
could need improvement in that area.
