[CentOS] proftpd wrap

Hi,

My ftpd is being abused.

Maximum login attempts exceeded from hosts:
   ::ffff:64.251.22.142[::ffff:64.251.22.142] : 24197 Time(s)

I had came across an article stating that proftpd with mod wrap can actually
block these IP using denyhosts.
I had googled but I did not see any proftpd rpm with mod wrap. Is there
anyone with a copy would like to share?
Or can someone share a spec file, so I can roll my own rpm.

I am running on CentOS 5.4.

Thanks
