[texhax] trouble with texhash and pst-algparser.pro

For reasons that are mysterious to me, my ability to create slideshows
using PowerDot failed on my laptop.  It turned out that dvips was
missing pst-algparser.pro.  When I put that file into my directory
(see below for how I found it) all was fine.  So I figured that would
be fixed by installing the DVD (August 2010) MacTeX.  The install went
cleanly, but I still was using the 2008 versions according to my log
file.  I did a texhash and discovered that now I was using my 2005
version!  I moved the old versions out of /usr/local/texlive.  Now
texhash was not found at all.  So I located the texhash in the bin
directory and ran that:

sudo /usr/local/texlive/2010/bin/uniersal-darwin/texhash

Then I needed to work in a fresh Terminal.  *WHEW*.  That was pretty

So I have some suggestions for the installation:

1. Could the MacTex installation do a texhash for users?

2. Could the texhash be smarter and look for the most recent version
instead of the oldest one?


Why was pst-algparser.pro "suddenly" not found?  Oddly, this file is
in the correct location in the 2008 distribution.

A google search led me to
and then
which gives

% $Id: pst-algparser.pro 350 2010-06-18 05:18:55Z herbert $
%% PostScript prologue for PSTricks algorithm parser
%% Version 0.02, 2010/06/08

But the version I have just installed from the 2010 DVD is:

% $Id: pst-algparser.pro 90 2009-01-30 10:58:51Z herbert $
%% Version 0.01, 2008/01/01

Aren't all packages upgraded for the DVD?
