Installing oci8 in AIX

I have an AIX 5.3 installation on a server that I'd like to host a php app on Oracle DB.
I'm compiling php with oci using the cmd :

./configure --prefix=/usr/local \
            --with-apxs2=/usr/local/apache2/bin/apxs \
            --with-config-file-path=/usr/local/apache2/conf \
            --with-gd --with-zlib-dir=/opt/freeware/lib \
            --enable-shared \
            --disable-static \
            --with-png \
            --with-zlib \
            --with-bz2 \
            --with-xml \
            --with-jpeg-dir=/opt/freeware/lib \
            --with-png-dir=/opt/freeware/lib \
            --with-xpm-dir=/opt/freeware/lib \
            --with-freetype-dir=/opt/freeware/lib \
            --with-oci8=shared,instantclient,/opt/oracle/instantclient_11_2

but the error appearing is at the last lines is:

checking for Oracle (OCI8) support... yes, shared
checking PHP version... 5.2.14, ok
checking size of long int... 4
checking Oracle Instant Client directory... /opt/oracle/instantclient_11_2
checking Oracle Instant Client SDK header directory... /opt/oracle/instantclient_11_2/sdk/include
checking Oracle Instant Client version... configure: error: Oracle Instant Client library version not supported

Dude!!! I need some light on this issue bigtime, tafadhali (please).:confused:
