| This only applies when os.name == 'posix'. Running an un-installed build of Python with the -S option causes the directory containing the standard dynamically-built modules not to be placed on sys.path. The build/lib.-/ directory containing those modules is added to sys.path by site.py rather than getpath.c, even though those modules are needed. This includes many modules on most Unix systems: array dbm math regex termios audioop dl md5 resource _testcapi binascii errno mmap rgbimg time bsddb fcntl mpz rotor timing cmath fpectl nis select _tkinter _codecs gdbm operator sha unicodedata cPickle grp parser _socket _weakref crypt _hotshot pcre _ssl xreadlines cStringIO _hotshot pwd strop zlib _curses_panel linuxaudiodev pyexpat struct _curses _locale readline syslog Perhaps the best way to fix this is to add the equivalent code to getpath.c. The relevant stanza in site.py is headed by a comment saying "especially for Guido". |

| We have lived this long without changing this that I don't think this needs fixing. Requiring the use of site.py when running from a build from a repository checkout seems totally reasonable to me. |

| Note that this does cause incompatibility between development copies and installed copies: $ python -S -c "import itertools; print itertools" <module 'itertools' from ...> $ ./python -S -c "import itertools; print itertools" Traceback (most recent call last): File "", line 1, in ImportError: No module named itertools |

| If we think once can reliably add the directory based purely on whether it starts with "build/lib.", and then potentially check for a suffix of "-pydebug" if we are in a debug build, I will support adding this to getpath.c to ditch the distutils import used by site.py. |

I guess the real question is how often to people actually have multiple versions of their built libraries in build/. |

| r83988 does really fix this issue in python 3.2, 8 years later, yeah! |

| Ooops, I didn't notice that Antoine did already updated this issue. Restore the resolution as duplicate since the superseder field is set. |
