You should define the PWGUI environment variable!!
Depending on which shell you are using:
setenv PWGUI something/espresso-3.0/PWgui-3.0
export PWGUI=something/espresso-3.0/PWgui-3.0

As far as I know, chdens.x has been merged into pp.x. From Changelog in 
the CVS version:
2005-09-13 22:30  giannozz

        * Doc/INPUT_CHDENS, Doc/INPUT_PP, PP/Makefile, PP/chdens.f90,
          PP/postproc.f90, PW/clean_pw.f90, examples/example05/README,
          examples/example05/run_example, examples/example16/README,

        chdens.x merged into pp.x - all functionalities are still there
        and it is still possible to do the two steps independently.
        The output is basically the sum of the two outputs with minor
        differences. Documentation and examples updated, GUI not yet.

You find how to use the "new" pp.x for both post-processing and plotting 
(old chdens.x) in espresso3.0/Doc/INPUT_PP

Hope this helps,
