error while compile and install snort in rhel5

Dear Experts:

Iam having rhel5.5, iam trying to configure snort hence as a requirments

downloaded the libpcap-1.1.1 compiled and installed the same by executing the following command:

./configure --prefix=/opt/snort/snort2.9 ; make && make install
---------
with the above command successfully got installed without any errors, after this did cd to daq-0.2, by executing the command i,e by pointing to the libpcap path like the below :

./configure --with-libpcap-includes=/opt/snort/snort2.9/include --with-libpcap-libraries=/opt/snort/snort2.9/lib


the above compile ends with the following error:

checking for pcap.h... (cached) yes
checking for pcap_lib_version... checking for pcap_lib_version in -lpcap... yes
checking for libpcap version >= "1.0.0"... no

    ERROR!  Libpcap library version >= 1.0.0  not found.
    Get it from http://www.tcpdump.org

-------------------------------------------------

Even though libpcap is installed while installing the daq it is not able to find the libpcap, please help.

After you compiled and installed pcap library, do following as root:

1. In directory /etc/ld.so.conf.d create file snort.conf, consisting of 1 line:

/opt/snort/snort2.9/lib

2. Run ldconfig

Now try to configure daq again

Sir , did as per the instructions and then executed the below command from the daq
./configure --with-libpcap-includes=/opt/snort/snort2.9/include --with-libpcap-libraries=/opt/snort/snort2.9/lib
-----------
with this compiled successfully then did make and make install. worked fine

Please suggest is it required to fix the above Error 1 or it is okay can be ignored the snort will not have problems with this error.
