# Problem regarding parcolumns package

I needed to use parcolumns packages which was not available on my system. I installed it and now am having some trouble. I followed following steps:

• Locate the package sauerj on CTAN website. I downloaded the zip, extracted the folder sauerj and ran following command for each .ins file in the folder: latex filename.ins which created .sty files in the same directory.

• Copy the entire directory to /usr/share/texmf-texlive/tex/latex and cd to that directory.

• I ran following commands in that directory: sudo mktexlsr, texhash.

Now I try to compile a simple code:

\documentclass[a4paper,20pt]{article}

\usepackage[total={6.5in,8.75in}, top=1.2in, left=0.9in]{geometry}
\usepackage{fancyhdr}
\usepackage{multicol}
\usepackage{ragged2e}
\usepackage{hyperref}
\usepackage{parcolumns}

\pagestyle{fancy}

I get following error:

If I remove \usepackage{parcolumns} line, the script works. But I need to use parcolumns package.

BTW, the sauerj.zip had files related to processkv.

does the directory you added via mktexlsr contain processkv.sty which should have been extracted from processkv.dtx by running tex on processkv.ins. If it isn't there there was a problem with the extraction, if it is there but tex didn't find it there was a problem with tex directory searching. –  David Carlisle Mar 27 '12 at 17:15
Are you using TeX Live? If so, using its package manager tlmgr to install parcolumns is better than doing this by hand as it resolves dependencies and updates files automatically if necessary. All you need to do is invoking sudo tlmgr install sauerj. –  diabonas Mar 27 '12 at 17:18
this question talks about parcolumns but the error is actually to do with updating your packages. run tlmgr update --self --all and you should be set; installing packages manually is a pretty tricky task –  cmhughes Mar 27 '12 at 17:22
