What we do is statically link Python into GDB, and then distribute
both GDB + Python. As long as the path to Python is inside the
configured prefix, the path to the Python libraries should be
"relocatable", allowing users to install the binary package anywhere
and GDB will always find them.

One thing we also do that's not done in the FSF version of GDB
is the following:

@@ -1680,6 +1680,10 @@ message == an error message without a stack will be printed."),
 #else
   Py_SetProgramName (progname);
 #endif
+
+  /* We override any value that the PYTHONHOME might have, as we want
+     to make sure that we use the Python library that comes with GDB.  */
+  Py_SetPythonHome (ldirname (python_libdir));
 #endif
 
   Py_Initialize ();

Some users have had their own version of Python which may be incompatible
with the version we ship in GDB, so we make sure that within GDB, we use
the Python that we built with.
