Yesterday I had trouble when configuring Apache 2.2 with PHP 4.4.2,
which caused Apache to crash (segmentation fault) when calling various
The hint to the answer resided in the /var/log/httpd-error.log file:

This obviously hinted at these functions (i.e php4-extensions) somehow
being doubly present and called.
Issuing a 'pkg_info | grep php' command was most illustrative, and
showed over a screen full of output like this:
mod_php4-4.4.2_1,1 PHP Apache Module
php4-bcmath-4.4.2_1 The bcmath shared extension for php
php4-bz2-4.3.10 The bz2 shared extension for php
php4-bz2-4.4.2_1 The bz2 shared extension for php
php4-calendar-4.4.2_1 The calendar shared extension for php
php4-crack-4.4.2_1 The crack shared extension for php
php4-ctype-4.4.2_1 The ctype shared extension for php
php4-dio-4.4.2_1 The dio shared extension for php
php4-domxml-4.4.2_1 The domxml shared extension for php
php4-exif-4.4.2_1 The exif shared extension for php
php4-extensions-1.0 A "meta-port" to install PHP extensions
php4-gd-4.3.10 The gd shared extension for php
php4-gd-4.4.2_1 The gd shared extension for php
[...more lines where those came from...]
Tadaaaah!! there we go: indeed several extensions were somehow not
removed properly when a previous upgrade to PHP 4.4.2 (from v4.3.10) was
As to the reason for this, go figure, I always install from the ports by
doing a 'make' 'make deinstall' 'make reinstall' sequence when upgrading...
Anyway, manually removing all PHP extensions using the various
individual 'make deinstall' sequences (and bluntly pkg_delete for pear).
Then, I cleanly redid the process for installing mod_php4 and the
extensions, and now all is working fine!
Tnx for thinking along with me, and beware of this potential pitfall! :)
