container startup error on missing gd.so

[quartje]

When the container of version 6.15.4 starts, an error is generated:

PHP Warning:  PHP Startup: Unable to load dynamic library 'gd.so' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20170718/gd.so (libpng16.so.16: cannot open shared object file: No such file or directory), /usr/local/lib/php/extensions/no-debug-non-zts-20170718/gd.so.so (/usr/local/lib/php/extensions/no-debug-non-zts-20170718/gd.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

It seems Engineblock does run without it.

I'm stil seeing this. Perhaps it's the php config that's broken?
