젠투 설치시 젠커널 컴파일 오류

안녕하세요. 리눅스를 처음으로 써보고자 하다가 막히는 부분이 있어 질문글을 올립니다.
처음에는 페도라를 설치하였다가, 주변의 권유로 인해서 젠투로 갈아타려고 하는데요.
여기에 나와있는 많은 문서들을 읽어보고 젠투가 어떠한 순서로 설치되는지 슬슬 감이 잡히기 시작합니다 (아직까지 모르는 것이 무지막지하게 많지만...)

여쭙고 싶은 내용은 아래와 같습니다.
genkernel --menuconfig all을 실행하고 아무것도 손대지 않은 상태에서 그냥 진행을 시켰습니다 (그리하는 것이 초보들한테는 좋다는 조언에 따라..)
그러면 아래와 같은 내용이 나오다가 커널 컴파일 오류가 나타납니다.

처음에는 아무것도 모른채 그냥 다 되었거니 하고 진행하였다가, 재부팅 시키니 그럽만 뜨고 아무것도 안나오더군요.
처음부터 설치하는 것을 5번째 실행하다가, 이제서야 이런 오류가 있었다는 것을 알았습니다 (다른 분들은 젠커널 하는대만 약 2-3시간 걸린다고 하길래.. 따져봤습니다).
에러 로그를 다 올리려니 너무 내용이 많기는 한데.. 보다 정확한 해결책 제시가 가능하실 거 같아 아래에 같이 붙입니다.

감사합니다.
