The PHP devs should try harder to not bundle common libraries and
instead push private changes upstream (IMHO).

You should really not use the system libgd, especially not on the
following systems:
- debian
- RHEL
- Centos

The problem still has to be fixed tho' :)

Are you using the bundled libgd, or an external one?

Description:
------------
I get an unresolved symbol when linking against system libgd.


Reproduce code:
---------------
Just running php-cli

Expected result:
----------------
Should work.

Actual result:
--------------
PHP Warning:  PHP Startup: Unable to load dynamic library
'/usr/lib64/php/extensions/gd.so' - /usr/lib64/php/extensions/gd.so:
undefined symbol: gdJpegGetVersionInt in Unknown on line 0
