JWS3.0-Optional rpms in the EWS installation guide for httpd zip

Customer notice that the links in the "lib" directory of EWS 3.0 httpd zip installation, points to missing files. For example:

lrwxrwxrwx. 1 root root  40 Aug 22 13:25 apr_dbd_pgsql-1.so -> /usr/lib64/apr-util-1/apr_dbd_pgsql-1.so
lrwxrwxrwx. 1 root root  38 Aug 22 13:25 apr_dbd_pgsql.so -> /usr/lib64/apr-util-1/apr_dbd_pgsql.so

"apr-util-pgsql" package is not required for httpd service to run, however it does contain the binary to satisfy the link.

Customer suggest it should be mention JBoss Web Server 3.0 installation guide. I think possible a "optional rpms" section, thats mention "apr-devel , apr-util-ldap , apr-util-pgsql , apr-util-odbc , apr-util-mysql , apr-util-openssl and apr-util-nss " package to satisfy the link
