@command_path affects only executables directly invoked by cvsweb.  And
cvsweb doesn't invoke diff directly [0], it invokes rcsdiff which then
again uses internally whatever diff it considers appropriate.

One thing to try: add this somewhere in your cvsweb.conf:

  $ENV{PATH} = '/home/www/apps/bin';

If rcsdiff uses $PATH, that could help.  If not, it might have a
compiled in path to the diff tool it's using.  HTH...

[0] By default, that is.  One can configure different diff tools for
    different MIME types with %DIFF_COMMANDS in cvsweb.conf.
