I'm sorry I don't understand the tetex installation process, but the a0poster package files don't get installed correctly, so \usepackage{a0poster} fails. bash-2.05b$ locate a0poster /usr/share/texmf/source/latex/a0poster /usr/share/texmf/source/latex/a0poster/a0poster.cls /usr/share/texmf/source/latex/a0poster/a0.tex /usr/share/texmf/source/latex/a0poster/a0_eng.tex /usr/share/texmf/source/latex/a0poster/a0size.sty /usr/share/texmf/doc/help/Catalogue/entries/a0poster.html There are no files in /usr/share/texmf/tex... Other packages show proper behaviour: bash-2.05b$ locate setspace /usr/share/texmf/source/latex/setspace /usr/share/texmf/source/latex/setspace/setspace.sty /usr/share/texmf/doc/help/Catalogue/entries/setspace.html /usr/share/texmf/tex/latex/misc/setspace.sty bash-2.05b$ locate fullpage /usr/share/texmf/source/latex/preprint/fullpage.drv /usr/share/texmf/source/latex/preprint/fullpage.ps /usr/share/texmf/source/latex/preprint/fullpage.ins /usr/share/texmf/source/latex/preprint/fullpage.dtx /usr/share/texmf/source/latex/preprint/fullpage.pdf /usr/share/texmf/doc/help/Catalogue/entries/fullpage.html /usr/share/texmf/doc/latex/preprint/fullpage.dvi /usr/share/texmf/tex/latex/preprint/fullpage.sty
Thanks for the bug report. Fixed in CVS. (please emerge tetex again)
