Yesterday I updated my MikTeX 2.9 packages, and suddenly I couldn't build package manuals any more, failing with the error {F:/texmf/fonts/enc/dvips/fontname/8r.enc} !pdfTeX error: pdflatex.EXE (file ec-inconsolata): Font ec-inconsolata at 540 not found ==> Fatal error occurred, no output PDF file produced! This is similar to a problem that people had last summer. Here is my solution: R uses the LaTeX inconsolata package to get some fixed-width fonts for the help pages. That package has been going through a lot of changes lately. The problem is that I updated the system copy of the packages (using "Maintenance (Admin) | Update (Admin)", but not the per-user copy (using "Maintenance | Update"). Since the per-user packages have priority, this meant I had a mix of obsolete and current packages visible to pdflatex, and it failed. Doing both updates seems to have fixed things. Duncan Murodch
