Thanks for all the information. it really served as a nice checklist of
things I had already checked and things I needed to check. Tomasz, your
suggestion was the critical one and your pointer to the "Problems with
texvc" page made all the difference. In particular, the section about
including the pathing in the render.ml file and recompiling did the
trick. I also consulted with several other colleagues on this issue as
well as my hosting company. The problem I had with texvc seems to
occur regularly in the shared hosting situation. Indeed, if you go to
google and search for the error string "Failed to parse (PNG conversion
failed; check for correct installation of latex, dvips, gs, and
convert)" you will find many sites suffering from this problem.
Fortunately, not only did I get a great list of things to check (and
explanations of why and how to check them) but also a couple of
alternatives to texvc which I was able to make work. I want to put my
notes (mostly other people's emails) together in an article and post
it. I was wondering where might be the best place. Certainly, it
would be useful in the installation documentations and as an addition
to the "Problems with texvc" page. Are there other points where it
would be useful?
Thanks Again
Roberto

These are just general debugging suggestions, things you should always
check when having problems running external programs from a PHP web app:

And in particular on FreeBSD, check the PATH environment variable *as it
is present in the web server and passed to the PHP program*. It very
likely does not contain /usr/local/bin, which is where many programs
installed via the ports system will be installed.
Indeed the $PATH seems to be the most common problem.
