If you're building PHP yourself, I suggest to build it with the bundled
libgd, and only to include support for the image formats that are
needed.  In the simplest case you just do

  ./configure … --with-gd

That requires to have libpng-dev installed.  If you also need JPEG
support, you have to install something like libjpeg-dev and do

  ./configure … --with-gd --with-jpeg-dir

Perhaps you have to explicitly specify the path to where libjpeg is
installed, but at least on my Debian Jessie that's not necessary.

Cheers,
Christoph
