try to apply patch on jQuery without success- packed result file unusable


I am very new to jQuery source work, so I guess I am asking some
really introductory stuff here.
I just grabbed the source from the svn tags 1.3.2 and would like to
apply a patch for the hidden filter bug (makes slideUp not work).
However when I run ant pack, and use the result file, the file seems
does not have $ defined- basically a lot of weird errors come up. Any
crash start guide for me to read?
