"--scrypt: unrecognized option "
Whats the problem?

As I remember this happens when you use newer cgminer versions which do not support scrypt anymore. I'm using 3.7.2 version and if I'm not mistaken this is the latest version which supports scrypt.
It's the LAST version to support gpu mining if im not mistaken.
downloaded 3.7.2.
and now this: [2014-02-06 17:27:41] Unexpected extra commandline arguments
Segmentation fault: 11
logout
what gpu are you using?
do you use batchfile or configfile to configure cgminer?
I have a Macbook pro #13 early 2011
It's a Intel HD Graphics 3000 512 MB. On board I think..
