[Rd] paths for install and libraries?

I've written a fairly elaborate package (called "eoa") that relies on
functions from several other packages. I've built the package into a zip
file on Windows using Hadley's devtools::build(binary = T) and have sent
the zip to a couple dozen people for testing. My package installs fine, but
some people are having trouble loading it. After library(eoa), they get
something like:

Error: could not load package tcltk2

In DESCRIPTION file, I use

Depends: tcltk, tcltk2, tkrplot
Imports: actuar,

If, after getting the "could not load" message, the user installs the
required packages by hand, everything works fine.

My understanding was that both the "Depends: " and the "Imports: " lines in
DESCRIPTION file direct R to automatically install required packages that
haven't been previously installed.

It doesn't appear to be working that way for me. There must be a simple
solution that I am obviously missing....

Any help would  be greatly appreciated!
