I installed Kile and Texlive 2011.
I wrote a very simple test document:
\documentclass[11pt]{article}
\usepackage{xltxtra}
\setmainfont[Mapping=tex-text]{Linux Libertine}
\begin{document}
Русский: Числовые выражения
English: Number expressions
\end{document}
When I run $ xelatex myfile.tex from command line it is properly compiled to pdf file.
But when I try to build it from Kile, it throws an error File xltxtra.sty not found.
How should I configure Kile or Texlive installation, so things work properly? My OS is Ubuntu 11.10.

~/.bashrcfile, but they should be put into a separate script in/etc/profile.d/directory, because.bashrcis only executed by interactive shells. – Maxim Nov 09 '11 at 08:12on 32 bits use: i386-linux
