Please read and fix it by your self, I can't give you all answer each time you get problem.
Ok. Understandable.
However, I did read the readme.md and followed the instructions in there (specifically for Gentoo) and this is not the first bitcoin-like wallet I compile on this PC. But this is the first time I get these errors.
As much as I understand it says I don't have a required OpenSSL header file even though I have OpenSSL installed.
