I have tried this but I can not see gd module in Apache. How did you test it?

Need to add LoadModule php_module libexec/apache2/libphp.so
in $PREFIX/etc/apache2/httpd.conf

But starting apachectl will error

[php:crit] [pid 24463:tid 24463] Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe.  You need to recompile PHP.
AH00013: Pre-configuration failed

I am starting to doubt apache2 + php8 ever worked in the first place

Edit: nvm, search around again and need to fix in httpd.conf

LoadModule mpm_prefork_module libexec/apache2/mod_mpm_prefork.so
#LoadModule mpm_worker_module libexec/apache2/mod_mpm_worker.so

echo "<?php phpinfo(); ?>">  $PREFIX/share/apache2/default-site/htdocs/info.php

localhost:8080/info.php
But still no gd subsection
