I should clarify: you want a build _layer_. This requires creating a
build profile that details the various dependencies your application
will use. When you create a build in this way, all the dependencies are
then slurped into a single file.
The Dojo documentation for creating layer profiles is here:
http://docs.dojocampus.org/build/index
and ZF has support for helping you create the build profiles in
Zend_Dojo_BuildLayer:
http://framework.zend.com/manual/en/zend.dojo.build-layers.html
Give that a try, and see if it helps things out.
IIRC, Dojo 1.5 or 1.6 offers some functionality around automating this,
but you'll need to read through the changelogs to verify.
