Is it possible to set Windows' search path from within R, or
to tell Windows how to find a DLL in some other way from
R? Specifically, if a package DLL depends on another DLL
the normal requirement is that the second DLL be in the
search path so Windows can find it (there are other tricks,
but they apply at the Windows level, not at the R level).

I haven't tried this, but can't you use Sys.setenv() to change the PATH 
to what you want?  Presumably you'll want to change it back afterwards.

might be relevant, especially the DLLpath argument to dyn.load.
