With the kind help of cweiske on IRC I realized pear install was
broken, i have nuked them one by one with pear uninstall -n
phpdocs/... and now
php ../phd/render.php -d doc-base/.manual.xml -o output_dir/ -f php -P PHP
works. Great :)
And finally, if I change all getChildrens to getChildren then it works
(and makes my otherwise quiet laptop fan go totally berserk so
something def happened) and dies here:
PHP Fatal error: Call to undefined method
phpdotnet\phd\Package_Generic_ChunkedXHTML::getReader() in
