    Split the network and netmask into separate terms and sort on netmask within network.

    knoppix@Microknoppix:~$ perl -MSocket -Mstrict -wE ' my @networks = qw{ }; say for map { $_->[ 0 ] } sort { $a->[ 1 ] cmp $b->[ 1 ] || $a->[ 2 ] <=> $b->[ 2 ] } map { my( $network, $netmask ) = split m{/}; [ $_, inet_aton( $network ), $netmask ]; } @networks;' knoppix@Microknoppix:~$

    I hope this is helpful.

[hippo]: How did you install libapreq2?
[vedagiri89]: that one is done by system team from the tar i guess
[hippo]: Really? Not using the one from the CentOS repository? Perhaps that's the problem.
[vedagiri89]: i need when this issue will come usually
[hippo]: How about mod_perl? Was that installed from the CentOS packge or from source?
[vedagiri89]: from the source
[hippo]: But is under vendor_perl in your error message so you are mixing up modules installed from the packager and by hand. That's rarely a good plan.
[vedagiri89]: the prm fine if i run file directly..not working if i run through apache http file
