Solve the following python programming problem given the following code:
def _make_ffi_library(ffi, libname, flags) : 
    import os 
    backend = ffi._backend 
    backendlib = _load_backend_lib (backend, accessor_int_constant, flags) 
    def accessor_function(name) : 
        key = ('function ' + name) 
        (tp, _) = ffi._parser._declarations [key] 
        BType = ffi._get_cached_btype (tp) 
        try : 
            value = backendlib.load_function (BType, name) 
except KeyError as e : 
            raise AttributeError (('%s: %s' % (name, e))) 
library.__dict__ [name] = value 
def accessor_variable(name) : 
        key = ('variable ' + name) 
        (tp, _) = ffi._parser._declarations [key] 
        BType = ffi._get_cached_btype (tp) 
        read_variable = backendlib.read_variable 
        write_variable = backendlib.write_variable 
        setattr (FFILibrary, name, property ((lambda self : read_variable (BType, name)), (lambda self, value : write_variable (BType, name, value)))) 
def accessor_constant(name) : 
        raise NotImplementedError (("non-integer constant '%s' cannot be accessed from a dlopen() library" % (name,))) 
def accessor_int_constant(name) : 
        library.__dict__ [name] = ffi._parser._int_constants [name] 
accessors = { 
        
} 
    accessors_version = [False] 
    def update_accessors() : 
        if (accessors_version [0] is ffi._cdef_version) : 
            return 
from.import model 
        for (key, (tp, _)) in ffi._parser._declarations.items () : 
            if (not isinstance (tp, model.EnumType)) : 
                (tag, name) = key.split (' ', 1) 
                if (tag == 'function') : 
                    accessors [name] = accessor_function 
else : 
                    if (tag == 'variable') : 
                        accessors [name] = accessor_variable 
else : 
                        if (tag == 'constant') : 
                            accessors [name] = accessor_constant 
else : 
                for (i, enumname) in enumerate (tp.enumerators) : 
                    def accessor_enum(name, tp = tp, i = i) : 
          ...

    
    

    Fix the buggy line: backendlib = _load_backend_lib (backend, accessor_int_constant, flags)

#Here is Python program to fix the buggy line: backendlib = _load_backend_lib (backend, accessor_int_constant, flags)

backendlib = _load_backend_lib (backend, libname, flags)
