teTeX is said (http://www.ctan.org/tex-archive/help/Catalogue/entries/csplain.html) to include the whole csplain package, which is composed of various tex files and a few symlinks. Those symlinks are missing : cslatex -> pdftex csplain -> pdftex pdfcslatex -> pdftex pdfcsplain -> pdftex Also, the csplain.fmt file is missing. It should be built with : tex -ini -enc /usr/share/texmf/tex/csplain/csplain.ini The cseplain.fmt file is probably needed too. Reproducible: Always Steps to Reproduce:
Well... I just found the following lines in fmutil.cnf : # - Czech / Slovak for ISO-8859-2 locale (see below for UTF8). Enable # "by hand", not by "fmtutil --enablefmt", because definitions for # ISO-8859-2 / UTF8 share the same name. then commented line to enable csplain. I don't really know why there's this restriction on Gentoo and not on Debian. It seems that the right thing to do to use csplain is not the `tex -ini', but just remove the comments here, run `fmutil-sys --refresh' and then `mktexfmt csplain' and `mktexfmt cslatex'.
MMmh... Well, it seems that the warning in the file means something like ``DON'T TOUCH'' : some of my documents that use \usepackage[T1]{fontenc} seems to have problems with them now. (e.g. \copyright doesn't place the `c' at the right place). It'd probably better to switch this bug report to WONTFIX, but we can maybe found why.
