I installed PHP5.4 from PPA ppa:ondrej/php5-oldstable in my Ubuntu 12.04.2.

Then all of my image processing scripts got broken. Turns out the php5-gd library isn't loaded.

$ php -a

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/20100525/gd.so' - /usr/lib/php5/20100525/gd.so: undefined symbol: gdGetC in Unknown on line 0

Interactive mode enabled

Here's some package installed in my machine related to GD (hope might help, let me know if you need to know details of other packages):

ii  libgd2-xpm                                    2.0.36~rc1~dfsg-6ubuntu2                GD Graphics Library version 2

ii  libgd2-xpm:i386                               2.0.36~rc1~dfsg-6ubuntu2                GD Graphics Library version 2

ii  libgd3                                        2.1.0-2~precise+1                       GD Graphics Library

ii  php5-gd                                       5.4.17-4+debphp.org~precise+1           GD module for php5

Is there any way to fix this?
