PHP can't be compiled from a Git checkout on Ubuntu 14.04 out-of-the-box.

Welcome to dependency hell.

Try compiling from a pre-compiled download.

The reason a Git checkout won't compile is because of dependency issues with Bison. Ubuntu 14.04 has Bison ~3.0.0 and Bison ~2.0.0 is required to compile PHP.

checking for bison... bison -y
checking for bison version... invalid
configure: WARNING: This bison version is not supported for regeneration of the Zend/PHP parsers (found: 3.0, min: 204, excluded: 3.0).
configure: error: bison is required to build PHP/Zend when building a GIT checkout!

Workaround

Here is a workaround to make apt-get build-dep php5 run successfully.

Fully remove MySQL (not just the relevant 5.6 packages)

It's very important that any and all MySQL packages and any configuration files are fully removed. You can check what mysql packages are installed by running dpkg -l | grep mysql, see What do the various dpkg flags like 'ii' 'rc' mean?

Uninstall the packages with a purge option: apt-get remove --purge <package name>

You might also need to manually remove some files. Read the message that the apt-get remove --purge prints and it will tell you if it isn't removing certain files and why it isn't removing them. You need to manually remove those files that apt-get doesn't remove. They will most probably be files somewhere inside the /etc/mysql directory.
Run apt-get build-dep php5

This makes apt-get build-dep php5 run successfully and will install MySQL 5.5!
Ensure libmcrypt-dev is installed.

Later when you try compile you will get errors complaining about readline or mcrypt e.g.:
```
configure: error: Please reinstall readline - I cannot find readline.h
```
All of these errors are solved by installing libmcrypt-dev. :) Took me way too long to figure this issue out.
```
apt-get install libmcrypt-dev
```
Fully remove MySQL again

Go through the process as you did in step 1 except this time it's 5.5 you're removing.
Install MySQL 5.6

Troubleshooting: When you try to compile you still get errors?

Ensure that libmcrypt-dev is installed.
