Topic: pear missing extensions needed for packages
It seems like one of the recent updates to pear disables the bulk of the PHP extensions from loading, which is causing an issue for me:
# sudo pear install phpunit/phploc
phpunit/phploc requires PHP extension "tokenizer"
theseer/fDOMDocument requires PHP extension "dom"
phpunit/FinderFacade requires package "theseer/fDOMDocument" (version >= 1.3.1)
No valid packages found
install failed
The tokenizer and dom extensions are both enabled on my system, but it seems that the pear script is now specifically choosing the extensions to load. This happens on php-pear-1.9.4-26.el6.remi.1. Downgrading to php-pear-1.9.4-20.el6.remi fixed the issue.
