Maybe the  problem came  of building  another emacs-24.3  in /usr/local/
...   I   met  another   problem   with   that.   So   I  sudo   rm   -r
/usr/local/emacs-24.3/ and I am going to  make another check. I keep you
informed.

Unfortunately, the same problem persists in boring me. I have even tried an "aptitude reinstall emacs24", nothing has changed. 

I got this result with a formula:

<#multipart type=alternative><#part type=text/plain>#+OPTIONS: latex:t


((p \to q) \to p) \to p
<#multipart type=related><#part type=text/html><p>
<img src="cid:_tmp_ltxpng_latex55421HL_fe33fb9aa807a803acea12fbcfe6cf88056fbc6b.png" alt=" ((p \to q) \to p) \to p " /><br  />
</p>
<#part type="image/png" filename="/tmp/ltxpng/latex55421HL_fe33fb9aa807a803acea12fbcfe6cf88056fbc6b.png" disposition=inline id="<_tmp_ltxpng_latex55421HL_fe33fb9aa807a803acea12fbcfe6cf88056fbc6b.png>">

Where you'll can see the image of Peirce Law, but I cannot send the message via Gnus because the message error: 

Creating LaTeX Image...
Failed to create dvi file from /tmp/orgtex5542CSR.tex
Auto-saving...

I do not understand. 

I send this message from Gmail  (Gmail-Tex displays the image), because I am unable to find our thread in the Group of this List  in Gnus, but it is another problem....

Best wishes and good evening, 

Jo.
