감 missing meaning in naver
I asked one of my friends about the meaning of 감 in the following sentence,

제가 못 가더라도 그자리 갈만한 사람이 가긴 해야 하잖아요
제대로 깜이 아니예요

She said to me it meant qualification.

The usual meaning that i am aware of is feeling and sense. I tried to look it up for other meanings in Naver yet could not come across anything that resembles the meaning of qualification at all. Naver seldom misses out on definitions except for very contemporary slangs. I wonder what is the deal for it.

Answer

Naver dictionary is just a mirror of 표준국어대사전(National standard Korean dictionary)
표준국어대사전 is quite conservative dictionary and it lack many words.

You can use Daum dictionary (http://dic.daum.net) as a complementary.

Answer

I think the word 감 you're thinking (feeling and sense, or "hang/gist" as in "I'm getting the hang/gist" of this -- this word, by the way, comes from the Chinese character 感, I think, but I could be wrong) and the word 깜 you're talking about are actually two different words.

I would say 깜 in your example loosely gets translated as "material" in English -- as in "he's not a good material/fit/candidate for that type of work", etc. And yes, as others have mentioned, 깜 is *very* colloquial...

Answer

깜 within the context is reduced form of 깜냥, which means ability for something. Informal, but standard.
It might be used like 제가/저는 깜이 안 돼요

Answer

감 has several meanings,

1) sense, feeling, sensitivity of something
2) base material
  e.g. 이 옷은 안감이 부드럽다 (Lining of this clothes is soft) 
3) someone who is qualified for something 
  e.g. 그는 좋은 신랑감이다 (He is a good potential husband) / 아이가 장군감이다 (The kid will become a strong/brave man like a general some day)
