Dojo build for dijit creates file containing only undefined; -

i'm creating custom build dojo application. i've created following profile.js:

var profile = {     basepath: "../../../",     releasedir: "./releases/custom",     packages: ['dojo', 'dijit', 'dojox' ],     cssoptimize: 'comments',     mini: true,     optimize: 'comments',     layeroptimize: 'comments',     stripcontrole: 'all',     selectorengine: 'lite',     layers : {         'dojo/dojo': {                      include: ['dojo/dojo', 'dojo/domready', 'dojo/_base/declare', "dojo/on", "dojo/dom-attr", "dojo/dom-class", "dojo/query", "dojo/_base/lang", "dojo/request/xhr", "dojo/parser", "dojo/_base/connect", "dojo/deferredlist", "dojo/store/memory", "dojo/store/observable"],                      boot: true,                      custombase: true            },          'dijit/dijit' : {             include: ["dijit/registry","dijit/form/textbox", "dijit/form/textarea", "dijit/form/combobox", "dijit/form/filteringselect", "dijit/form/checkbox", "dijit/form/button"],             boot: true,             custombase: true         },     }, } 

the dojo/dojo.js created, dijit/dijit.js contains template text:

//>>built

undefined;

however, file dijit.js.uncompressed.js created correctly (998 kb).

why dojo build behaves way? error in configuration? dojo documentation quite enigmatic.

--edit--

it seems problem specifying output files. after changing 'dijit/dijit'enter code here 'dojo/dijit' file dijit.js created in dojo subdirectory. if want create build custom name, need create in dojo subdirectory too. otherwise empty file (containing undefined;) created.
