Reinhard:

Thanks for the quick response.

I generally don't.  However, having moved the 2008 directory somewhere
else, I needed to be sure I was running the new version.  Are you
saying I should have done this:

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

?  I don't see how that would have made much difference.

I don't have those variables in my env.  I have TEXINPUTS pointing to
inside my powerdot directory.

According to my log file, I am now using TL-2010.  But I moved the old
versions to a new directory, /usr/local/texlive/old, so I looked into
that.  The file pst-algparser.pro is intact there.

I get the sense that a user is supposed to know a lot about the guts
of where things are, where things were and how the entire system
works.  The problem appears to be that I had previous systems, 2005
and 2008.  I don't see why a new installation should use the old
stuff.  I expect that when I install a program I will from then on
have the new version and that I won't have to do anything.  At minimum
the installation could warn the user to read some page somewhere.

Regards,

Tom
