package air bug

I have a mobile air project which i compile to a swf. When trying to package the swf using the ADT command i get an exception: Unable to run aapt  The ADT jar is in the SDK i've downloaded from adobe  I found this open bug on the subject https://issues.apache.org/jira/browse/FLEX-28995.  I've tried running it on ubuntu, red hat , 64bit and 32 bit - same error everytime.  I'm sure many people use linux machines to package their projects using the ADT tool . I just can't figure out what's wrong.  Thanks O.
