I\'m trying to install this extension but it fails in the configuration phase. I\'m on ubuntu 12.04 and I have just installed these packages:
You need to install php-raphf from your package manager.
for me i installed the module using the following. In your case you should be able to switch out yum for apt-get.
sudo yum install php-raphf
sudo yum install php-propro
sudo pecl install pecl_http
The you will need to add extension = http.so to your php.ini file. But it looks like you have already done that.
pecl does not actually install the .so file that you are looking for.
