이렇게 촤르륵 뱉어낸다.

sudo apt-get update

sudo apt-get upgrade

해보고 다시 해봤는데도 안 되고, 

인터넷 찾아보니

sudo apt-get install libgcrypt11-dev

sudo apt-get install libgcrypt20-dev

sudo apt-get install libssl1.0-dev

추가 설치해도 실패.

그러다가

./configure --disable-ssl

(./configure을 해줬던 위치에서.)

을 해준 뒤, 

make clean 

하고 다시

make 하니, 잘 되었다.

해결.

끝.
