I have installed the MacTex distribution successfully (several times
now!) and I am trying a short mathematical file.  The system cannot find
any ' theorem' macros.  I am using amsart and the packages amsmath,
amssymb, amsthm --- it does not complain that it cannot find these.  But
it refuses to have anything to do with any spelling of 'theorem'.  I have
tried 'Theorem" 'thm' etc but none of these work.  The equation, its
arrays, fonts etc seem to work OK.  But where are the theorem macros
hiding?

I'd be grateful for any suggestions.

you have to declare theorems with

where <name of environment> is what you will
use with

\begin{theorem}
...
\end{theorem}

etc.  <heading text> is usually Theorem,
Corollary, etc.  (optionsl) <reference
number> is the sectioning within which
you want these things numbered, so you
would have "Theorem 3.1" for the first
theorem in section 3.  there are three
different theorem styles.
