php5升级后安装php mongo驱动程序时出错

我用这种方式将我的php5版本从5.4升级到5.6(debian 7.9):

我补充道

deb http://packages.dotdeb.org wheezy-php56 all
deb-src http://packages.dotdeb.org wheezy-php56 all

到我的/etc/apt/source.list文件,然后:

apt-get update
apt-get install php5

一切正常:

php --version
PHP 5.6.16-1

但我需要升级我的php mongodb驱动程序,我收到以下错误:

pecl install mongodb

我安装了openssl和libssl-dev.任何的想法 ？

我有同样的问题和以下命令为我工作.

apt-get install pkg-config

sudo apt-get install -y autoconf g++ make openssl libssl-dev libcurl4-openssl-dev pkg-config libsasl2-dev libpcre3-dev
sudo pecl install mongodb
