Can't ./configure Nemsis and Libnet

Hi,

I am a newbie, and am having issues configuring nemsis 1.4 with the
libnet library. Ultimatley I would like to run a perl script that
referecnes the the Net/Packet.pm module. When I configure Nemsis I get
the following error:

ERROR! Libnet library not found, go get it from
http://www.packetfactory.net/projects/libnet/
or use the --with-libnet-* options, if you have it installed
in unusual place

Does anyone know how to configure the Nesmsis module with libnet
libraries? I have already configured libnet and did a make..make
install.

Thanks

Newbie
