Removed and then reinstalled php-common via yum. Now no virtual hosts?

Using yum I wanted to install the php-gdlibrary, however there was a dependency issue with php-common preventing me from installing php-gd. So after some digging I found this article on SO. I followed the instructions and removed php-common. I then reinstalled php-common. After that I was able to install php-gd without issue. However, I tried loading up my website and I find that the virtual hosts file is not being parsed and only the default site comes up. Even if I croaked the PHP install I would not think that it would mess up the virtual hosts. Or would it? Thanks.
