[PHP-INSTALL] PHP 5.6.1 and OCI8 Extension question

Hey guys,

I just compiled oci8 and pdo_oci for *PHP 5.6.1* to add to my PHP 
because it didn't come with my linux distro, but I'm getting this:

PHP Warning:  PHP Startup: Unable to load dynamic library 
'/usr/lib64/php5/extensions/oci8.so' - libnnz11.so: cannot open shared 
object file: No such file or directory in Unknown on line 0

PHP Warning:  PHP Startup: Unable to load dynamic library 
'/usr/lib64/php5/extensions/pdo_oci.so' - libnnz11.so: cannot open 
shared object file: No such file or directory in Unknown on line 0

I compiled it using the libraries from Oracle 11g Express, which is what 
I have on my Linux.

What can cause that?

Thanks,
