I'm surprised you ever >>heard<>remembered<< it.
Anyway, problem solved by installing texlive locally, using the install-tl-unx.tar.gz scripts from
That just installs over the net, which is pretty quick, ~70mins, from a dreamhost shell. And it "just worked" immediately. So the mathtex public web service is back up and running. But texlive takes 3GB (would be 4GB, but I omitted all the foreign language stuff). And strathclyde's /home is a 4TB disk with ~1.5TB free, so that one app takes ~1/500-th of the available space. I wish they'd install it under /usr/local/ once and for all, where it belongs, but support@dreamhost didn't seem interested in doing that.
Yeah, nowadays there are several better solutions. But I wrote and gpl'ed mimetex back in 2002, and mathtex a few years later, at which time they were pretty much the only solutions. And lots of people who started using it back then are apparently finding it good enough, so that the trouble to change isn't worth the effort.
