Trying to get Spotify-adblock.so working

[Pablo_v0.1]

Hey, I recently started using gentoo and It has been great, but a github programm that I used to use in arch It's no longer working; that being spotify adblock https://github.com/abba23/spotify-adblock
Giving me this output when I try to run it:

Does /usr/local/lib/spotify-adblock.so have a DT_NEEDED entry to cause it to load a library which would provide that symbol? If not, why not? If so, why does the library not provide it? What library would you expect to provide that symbol? How did you build/install this file?
