Compiling error

[masterseo2000]

Hello!
Great script!
Unfortunately we are having issues compiling the packages: We are able to do the .configure but we are getting errors while running .make. Below is the error
FYI we are running:
centos 6.8
PHP 5.5
We have successfully installed libspf2 development library:
[root@Application_Hosting1 php-spf]# rpm -qa libspf2
libspf2-1.2.10-5.20150405gitd57d79fd.el6.x86_64
[root@Application_Hosting1 php-spf]# rpm -qa libspf2-devel
libspf2-devel-1.2.10-5.20150405gitd57d79fd.el6.x86_64

This is the Error
