In Debian based distros you can specify which interface dhcpd listens on in 

/etc/defaults/dhcp


Otherwise, you could listen on all interfaces but have an empty configuration stanza in your dhcpd.conf for the networks and interfaces you _dont_ want to supply addresses to.

I think this is documented in the example dhcpd.conf that comes most distros's

something like
if you have 

eth0 = 192.168.9.1/255.255.255.0
ppp0 = 192.168.10.1/255.255.255.0

subnet 192.168.9.0 netmask 255.255.255.0 {
# empty configuration section so that DHCPD understands the network
# but issues no addresses on eth0 
}

subnet 192.168.10.0 netmask 255.255.255.0 {
#configuration to bind to ppp0 interface
  range 192.168.10.10 192.168.10.20;
  option broadcast-address 192.168.10.255;
  option routers 192.168.10.1;
}
