[tex-live] zsh path problems

[Pau]

Hello,

I installed texlive 2010 on a Fedora 14 laptop.

My shell is zsh

I have it on my path:

deukalion(pts/23)| echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/sbin:/opt/local:/opt/local/bin:/usr/local/texlive/2010/bin/i386-linux

But then,

deukalion(pts/19)| texexec ISAEI.tex
MTXrun | kpse fallback with progname 'context' initialized in 0.06 seconds
TeXExec | processing document 'ISAEI.tex'
TeXExec | no ctx file found
TeXExec | tex processing method: context
TeXExec | TeX run 1
TeXExec | writing option file ISAEI.top
TeXExec | using randomseed 70
TeXExec | tex engine: pdftex
TeXExec | tex format: cont-en
This is pdfTeXk, Version 3.141592-1.40.3 (Web2C 7.5.6)
 %&-line parsing enabled.

kpathsea: Running mktexfmt cont-en.fmt
I can't find the format file `cont-en.fmt'!
TeXExec | runtime: 1.840694

I also experienced problems with matplotlib when using the LaTeX
module; it didn't find it.

What am I doing wrong?

thanks,

P.
