when I try to install lastest version django on lastest jython version, 
get "couldn't make directories". It seems ntpath.isdir failed.

This is a bug/"feature" in the MSVCRT stat function, which Jython uses through jna-

#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>

int main(void) {
  struct stat foo;
  int retval = stat("c:\\Documents and Settings\\", &foo);
  fprintf(stderr, "stat returned %d\n", retval);

% ./stat
stat returned -1
stat: No such file or directory

If you remove the trailing \, it works fine.

I think this problem still exists in 2.5alpha3

Here is my workarounds

in lib\

def makedirs(path, mode='ignored'):
    """makedirs(path [, mode=0777])

    Super-mkdir; create a leaf directory and all intermediate ones.

    Works like mkdir, except that any intermediate path segment (not
    just the rightmost) will be created if it does not exist.
    The optional parameter is currently ignored.
    sys_path = sys.getPath(path)
    if File(sys_path).mkdirs():
        if File(sys_path[:-2]).mkdirs():

    # if making a /x/y/z/., inexplicably fails. So 
we need
    # to force it
    # need to use _path instead of path, because param is hiding
    # os.path module in namespace!
    head, tail = _path.split(sys_path)
    if tail == curdir:
        if File(_path.join(head)).mkdirs():
            if File(_path.join(head)[:-2]).mkdirs():
    raise OSError(0, "couldn't make directories", path)

This issue still exists in 2.5b1; I am experiencing the issue when
trying to install Django on jython.

I am attaching a patch to which solves the problem
on my Windows machine.
