Something seems to have changed either in my Sage or my Python
installation, but I can't diagnose it :
I wanted to compile (again) the sagetex documentation. Compiling
sagetex.dtx was a breeze (pdflatex sagetex.dtx ; sage sagetex.sagetex.sage
; pdflatex sagetex.dtx).
pdflatex example.tex went OK. However, sage can't evaluate the resultatn
example.sagetex.sage :
charpent@eee-ec:/usr/local/sage/local/share/texmf/tex/generic/sagetex$ sage
example.sagetex.sage

**** Running Sage on example.sage failed! Fix example.tex and try again.
A bit of googling led me to
this<http://ask.sagemath.org/question/1449/sage-uses-system-wide-python>,
which inspired me to go to $SAGE_ROOT/local/lib/python and do ln -s
site-packages/Ipithon/* . No success... Nor did sage PYTHONNOUSERSITE=yes
example.sagetex.sage
Could some kind soul point me to the direction of my stupidity ?
