My apologies for not responding more promptly. I got sidetracked from this over the holidays. Here's an example of console output from the ivy:retreive ant call. I see at the bottom of the log that it thinks the symlink failed to create and throws an exception, even though this is not the case.
Could you send us the console output when running Ant in verbose mode?

Subject: Retrieve symlink="true" on Windows
We are attempting to implement our build on Windows after having the ant+ivy
solution working well on Linux for about a week now. We were hoping to use
symlinking for compile-time dependencies as on Linux, but we are getting odd
behavior. After jumping through a few hoops with Cygwin 1.7, Ivy appears to be
creating working symlinks in our classpath directory for each project. However
it also appears to be copying the .jar files also! (see attached jpg)
Has anyone seen this before or have experience with using Ivy symlinks on
