Hi, I just upgraded to Fedora Core 2, which includes tetex-2.0.2. It does not include prettyref.sty, which is used by LyX. I traced the problem back to the source packages of tetex. I found that prettyref.html is included (in the texmf archive), but this is the only filename including prettyref in the source archives. I'm pretty sure that it was included with tetex-1.x .
Any comments? Thanks for any help, Ben Stanley
