Thanks for replying. :)
Well, it's not only about the local server - this is just one integrated functionality (which I need in the first place). I'd like to exclude as much functionality as possible to a command line tool which then can be included in different applications.
Your suggested options all look complicated (to me) and currently I feel quite frustrated because none of my approaches does work as I expected it (which again is just my lack of knowledge on this level).
I continued to figure out about the Segment error I got and avoided it by putting also all the aliases to the neko lib as well. It seems to run fine now from the terminal - but I need to start this as NativeProcess in Adobe AIR - and then again it won't find the library but print dyld: Library not loaded: @rpath/libneko.2.dylib in the stdoutput.
And of course I tried to find out how to create a static linked version of neko (which I hoped neko_static would do) - but I think I don't get it.
Well - I'll try to continue - but for now I feel a little helpless. :/ Boy what a day.
