! LaTeX Error: File `erewhon.sty' not found.
From http://www.ctan.org/tex-archive/fonts/erewhon/ a have file erewhon.tds.zip. There is also readme descriptions to install font, but for Linux with MikTeX. I have Texmaker and the description doesn't work.
"root of the folder you use for personal additions to the TeX trees" is maybe
/usr/share/texmf-texlive, i copied there directories doc, fonts, tex from unzip erewhon.tds. But what next? Thank you.
