3. Package with:
   

   rpmbuild -bb --with mysqlnd --define "rhel 5" SPECS/php-5.3.2-remi.spec
   

4. To install via yum, change to the directory where rpms are located and recreate the repodata via:
   
   createrepo .
5. Note: you may need to install some of the missing dependent devel packages. I used a combination of base, epel and remi repository to install the dependencies.
