Installing PECL uploadprogress Extension

A status report said

Upload progress Not enabled
Your server is capable of displaying file upload progress, but does not have the required libraries. It is recommended to install the PECL uploadprogress library (preferred) or to install APC.

pecl was already installed so this part is easy

pecl install uploadprogress

But is concludes with

configuration option "php_ini" is not set to php.ini location
You should add "" to php.ini

A little perverse in Ubuntu. I added

root@helen:/etc/php5/conf.d# cat uploadprogress.ini
; configuration for php pecl uploadprogress module

and reloaded Apache
