I had a working installation of LyX under FreeBSD, but at some point fairly recently (I'm not sure the exact circumstances), my LyX installation can't produce PDF files anymore because (almost) all document classes are marked unavailable. Googling has been no help - the common recommendations of running (from LyX) "Tools => Reconfigure" and (from the command line) "fmtutil-sys --all" have not solved the problem.
The document that I am currently working on uses the "article" class, and under /usr/local/share/texmf-dist/tex/latex/base there is a file "article.cls" (among other *.cls files). I'm at a loss. Can anyone shed light on what might be wrong? (I've already posted this to a FreeBSD mailing list without success so far.) -- Will
