Problem with deep directory structure

[Richard Suematsu]

I trying to setup my own repository using the Ivy Install ant task and 
its mostly working for me, but I'm having a problem with the jai_codec 
jar.  I do this-

<ivy:install organisation="com.sun.media" module="jai_codec" 
revision="1.1.2_01" from="ibiblio" to="local-repository" 
overwrite="false" />

I get the error-

missing artifact [ com.sun.media | jai_codec | 1.1.2_01 
]/jai_codec.jar[jar]:
/home/rich/.ivy/cache/com.sun.media/jai_codec/jars/jar-codec-1.1.2_01.jar 
file does not exist

Instead of creating the directory structure com/sun/media like it is on 
the Maven repo, it creates a com.sun.media folder.

Any ideas?

Thanks,
Rich
