zephir_parser extension not loaded

I'm running on ubuntu 14.04 and I installed php5.6. I'm trying to do the Hello world with Zephir but when I compile my project with :

zephir build

I got this error :

zephir_parser extension not loaded, compiling it

PHP Warning:  copy(modules/zephir_parser.so): failed to open stream: No such file or directory in /root/zephir/Library/Compiler.php on line 282
Zephir\Exception: The zephir parser extension could not be found or compiled!

Any idea ?

Edit

I reinstalled these packages :

php5-json php5-dev libpcre3-dev

I tried this command line :

./bin/zephir compile

And while compiling I have another error :

Copying new kernel files...
PHP Fatal error:  Call to undefined function Zephir\utf8_decode() in /root/zephir/Library/Compiler.php on line 2202

Solution

I solved my problem by reinstalling php with libpcre3-dev and install this :

apt-get install php5.6-xml

to solve the fatal error on the utf8_decode()
