-Wl,-rpath=\$ORIGIN``. From a Makefile, you need to say
something like ``gcc -Wl,-rpath=\$$ORIGIN``.
+* On some Linux distributions, notably Debian, the ``.so`` files of
+ CPython C extension modules may be compiled without saying that they
+ depend on ``libpythonX.Y.so``. This makes such Python systems
+ unsuitable for embedding if the embedder uses ``dlopen(...,
+ RTLD_LOCAL)``. You get the error ``undefined symbol:
+ PyExc_SystemError``. See `issue #264`__.
