hi again
two things:
1) when a problem has been solved please tag this thread as SOLVED
2) instead of appending further questions on a week old thread, it's better to create a new thread

about your question on how to use mkdfa.pl, you can't expect everyone to know what this is, so please add some links or explanations on what you talk about

because I am such a helpful soul I googled it and found out it is a part of gramtools which is part of the voxforge project

since this is very specific I'd suggest you use the Julius Forum (http://julius.sourceforge.jp/forum/) instead of this forum (maybe I'm wrong but my guess is that this thread won't get any more posts)
