64비트 Ubuntu에서 32비트 Python을 실행할 수 없습니다: 공유 라이브러리 로드 오류: libutil.so.1

64비트 Ubuntu 12.04에서 32비트 버전의 Python을 실행하려고 합니다. 이 특정 바이너리를 실행하는 방법은 여러 가지가 있지만 해결 방법보다는 오류의 원인을 이해하는 데 더 관심이 있습니다.

내가 받은 전체 오류는 다음과 같습니다.

/build/toolchain/lin32/python-2.7.1/bin/python: error while loading shared libraries: libutil.so.1: cannot open shared object file: No such file or directory

ldd누락된 정확한 라이브러리 경로를 확인하기 위해 자신의 컴퓨터에서 실행되는 동일한 시스템을 사용하는 친구가 있습니다 .

$ ldd /build/toolchain/lin32/python-2.7.1/bin/python
    linux-gate.so.1 =>  (0xf77c5000)
    libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf778e000)
    libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xf7789000)
    libutil.so.1 => /lib/i386-linux-gnu/libutil.so.1 (0xf7784000)
    libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xf7758000)
    libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf75ae000)
    /lib/ld-linux.so.2 (0xf77c6000)

내 시스템에서 libutil.so.1 라인에 대해 다음을 얻습니다.

libutil.so.1 => not found

흥미롭게도 내 컴퓨터에는 내 친구와 동일한 공유 라이브러리가 있습니다.

$ ls /lib/i386-linux-gnu/libutil.so.1 
/lib/i386-linux-gnu/libutil.so.1

그렇다면 이 라이브러리가 있는데 왜 Python이 이를 찾을 수 없습니까?

최신 Python이 잘 실행된다는 점은 주목할 가치가 있으며, 툴체인에 있는 Python 2.7.1의 64비트 버전도 잘 작동합니다.

업데이트: 이것은 strace 출력입니다.
