[Mediawiki-l] 1.4.0 works but texvc doesn't (FreeBSD 5.3)

[David Gerard]

I've installed the prerequisites for 1.4.0 and then 1.4.0 itself as
per http://meta.wikimedia.org/wiki/Running_MediaWiki_on_FreeBSD on my
FreeBSD 5.3 box.

The wiki is working just fine, but texvc isn't. make ran clearly and
there's what looks very like a binary there, but it isn't working.
The symptom is that you put a piece of text in the page, e.g.
<math>a \over b</math> and, instead of a nice PNG, you get:

  "Failed to parse (PNG conversion failed; check for correct installation
  of latex, dvips, gs, and convert): a \over b"

What I have here:

* latex, dvips, gs and convert are all present in /usr/local/bin .

* Per the README, I put  putenv("PATH=".getenv("PATH").":/usr/local/bin");
near the top of LocalSettings.php .

* The web server runs as user www:www, and the
/usr/local/www/data/mediawiki-1.4.0/ directory and everything under
it has permissions 644 or 755 and is owned by www:www.

* images/tmp exists and contains TeX files, so it's generating those, just
failing to render them. But we could have guessed that.

* no errors generated by this in /var/log/httpd-error.log .

* Brion suggested on irc to make sure PHP safe mode is off. I *think* it
is, looking at the config files.

Any clues? Is there some obvious newbie 'duh' I've missed?
