Hi Jay,

I do not know if this is your problem, but I could not build/install
extensions because I was missing some static libraries. In my case,
I needed to install 'yum install readline-static' before it would
successfully build and install. Try a manual build and see what libraries
it cannot find and add the static versions. Then the install should
complete.
