APC doesn't install properly on 5.6

[abductedMind]

If you run apt-get install php-apc you will get Makefile:214: recipe for target 'apc_zend.lo' failed.

How do I get APU working with this set of docker configurations for PHP 5.6? apt-get install php-apc runs to the end without error but this method doesn't result in a properinstall of apc cache.

Releated:
#68

Installing apc from Debian apt-repos does not work (we have a fix to prevent them from installing in #542) since it is compiled and created for the Debian provided php. The php we provide in the images is as close to upstream releases as possible, so it is built from source. If you need any extensions then you have to use the provided docker-php-ext-* scripts in the images and/or pecl (as noted in the Docker Hub docs and #68).

FROM php:5.6
# this a version noted as working for php 5.6 on #68
RUN pecl install apcu-4.0.11 && docker-php-ext-enable apcu
# php -m | grep apcu
# apcu
