configure + header files

I am trying to port ettercap-NG-0.7.3 to my iPhone 4. I downloaded the tar.ga package. I installed, unpacked, configured, but receive multiple errors. I combed thru the conf.log and fixed the pthread error so far. My question, the log shows missing header files. I go to google and type Koders code search <name of header>, I download and place it into the include folder of my phone. Not ettercap. So I re configure and still receiving the missing header error. More specifically it says

Code:

---

checking dl.h usability ...no
checking dl.h presence ...no
checking for dl.h ...no

---

What am I doing wrong?
By the way, I know just the other day I was asking about linked lists but I got bored with it and have been messing around with this. This is not a job, not for school, it's a hobby so. I hope this is not a big deal the jumping around. Thanks

I figure that I am adding the header files to the phone instead of the ettercap program. Now if I go into the ettercap include folder, it's not regular header files like malloc.h they have an ec_ prefix. I can't figure this out forthe life of me. A push in the right direction would be awesome!
