Problems with Apache-2.2.8 & PHP5 (+extensions) ports

[Peter Boosten]

Hi all,

Here's the situation: FreeBSD 7.0-RELEASE-p1, apache-2.2.8 from ports 
and php5:

php5-5.2.6          PHP Scripting Language
php5-bz2-5.2.6      The bz2 shared extension for php
php5-ctype-5.2.6    The ctype shared extension for php
php5-dom-5.2.6      The dom shared extension for php
php5-extensions-1.1 A "meta-port" to install PHP extensions
php5-gd-5.2.6       The gd shared extension for php
php5-gettext-5.2.6  The gettext shared extension for php
php5-iconv-5.2.6    The iconv shared extension for php
php5-imap-5.2.6_1   The imap shared extension for php
php5-mbstring-5.2.6 The mbstring shared extension for php
php5-mcrypt-5.2.6   The mcrypt shared extension for php
php5-mhash-5.2.6    The mhash shared extension for php
php5-mysql-5.2.6    The mysql shared extension for php
php5-pcre-5.2.6     The pcre shared extension for php

php5-spl-5.2.6      The spl shared extension for php
php5-tokenizer-5.2.6 The tokenizer shared extension for php
php5-xml-5.2.6      The xml shared extension for php
php5-xmlreader-5.2.6 The xmlreader shared extension for php
php5-xmlwriter-5.2.6 The xmlwriter shared extension for php
php5-zlib-5.2.6     The zlib shared extension for php

I've downloaded Joomla 1.5 from their site and installed it in my 
webroot, configured it with sample data and it works.... except for (so 
far) two links:

Whenever I click these, my browser wants to save a blank php-page, 
Apache reports this:

[notice] child pid 31685 exit signal Illegal instruction (4)

and my /var/log/messages state:

kernel: pid 31685 (httpd), uid 80: exited on signal 4

I've reinstalled all my ports with portupgrade -af (as suggested by a 
google search result), but still it keeps doing this. On my other 
machine (6.3, apache from ports, but php installed from source) Joomla 
runs flawlessly.

Anyone seen this (a solution would be nice :-) )?

Thanks in advance.

Peter
