사용가능한 Python 모듈들을 알아보기 위해 python 인터프리터에서 전체 모듈보기 명령어를 입력했는데, 다음과 같은 오류 메시지를 확인했다.
pchero@MyDebian:/usr/lib/pymodules/python2.7$ python
Python 2.7.3 (default, Mar 13 2014, 11:03:55)
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> help('modules')
Please wait a moment while I gather a list of all available modules...

그리고 Hang 이 걸린듯 더이상 진행되지 않았다.
해결법을 찾던 도중, http://blog.rabbitvcs.org/archives/312 에서 비슷한 현상에 대한 해결법을 찾았는데 뭔가 완벽하진 않았다.
http://stackoverflow.com/questions/13301100/python-fail-to-display-list-of-modules 여기도 역시…
내용인 즉, help(‘modules’) 를 입력하기 전에 gtk 모듈을 먼저 load 하라는 것인데.. 깔끔하지 않았다.
