<br>Thank you for the help.<br>The unifiedInstaller from <a href="http://plone.org">plone.org</a> seems to have a Python package that corrects this "stack size" issue.<br><br>After installing GNU versions of "tar", "make", "gcc" and "ln" on AIX-5.3, I followed, step by step, the install.sh script from unifiedInstaller bundle using bash shell. I continued progressing and correcting some small AIX environment differences.<br>
It worked very well. Many thanks to the Plone community and the unifiedinstaller!<br><br>Marcello Bax<br><a href="http://Paradigma.com.br">Paradigma.com.br</a><br><br><div class="gmail_quote">On Wed, Mar 19, 2008 at 3:54 PM, Dieter Maurer <<a href="mailto:dieter@handshake.de">dieter@handshake.de</a>> wrote:<br>

</div>Definitely. Almost surely, you see precisely this problem (C runtime<br>
stack too small).<br>
