You're running dvips, and you encounter a stream of error
messages, starting with "Mismatched mode". The mode is the
default used in your installation - it's set in the dvips
configuration file, and ljfour is commonest (since it's the
default in most distributions), but not invariable.
The problem is that dvips has encountered a font for which it must generate a bitmap (since it can't find it in Type 1 format), and there is no proforma available to provide instructions to give to Metafont.
So what to do? The number 8000 comes from the '-Ppdf' option
to dvips, which you might have found from the answer
"wrong type of fonts". The obvious
solution is to switch to the trivial substitute '-Pwww',
which selects the necessary type 1 fonts for PDF generation,
but nothing else: however, this will leave you with undesirable bitmap
fonts in your PDF file. The "proper" solution is to find a
way of expressing what you want to do, using type 1 fonts.
