Hi, I was typing out the distutils package this morning and hit a wall within a few minutes of running it. I got it using the "Easy Install" script found here: http://peak.telecommunity.com/DevCenter/EasyInstall#installing-easy-install To test the package, I tried using it on PyCrypto, found here: http://www.amk.ca/python/code/crypto.html After unzipping that package to a temporary directory, I ran distutils from the command line as follows: L:\Temp\pycrypto-2.0.1>python setup.py bdist_wininst Here's the traceback that gave me: L:\Temp\pycrypto-2.0.1>python setup.py bdist_wininst running bdist_wininst running build running build_py running build_ext Traceback (most recent call last): File "setup.py", line 164, in ? core.setup(**kw) File "L:\Python24\lib\distutils\core.py", line 149, in setup dist.run_commands() File "L:\Python24\lib\distutils\dist.py", line 946, in run_commands self.run_command(cmd) File "L:\Python24\lib\distutils\dist.py", line 966, in run_command cmd_obj.run() File "l:\python24\lib\site-packages\setuptools-0.6c7-py2.4.egg\setuptools\comm and\bdist_wininst.py", line 37, in run _bdist_wininst.run(self) File "L:\Python24\lib\distutils\command\bdist_wininst.py", line 107, in run self.run_command('build') File "L:\Python24\lib\distutils\cmd.py", line 333, in run_command self.distribution.run_command(command) File "L:\Python24\lib\distutils\dist.py", line 966, in run_command cmd_obj.run() File "L:\Python24\lib\distutils\command\build.py", line 112, in run self.run_command(cmd_name) File "L:\Python24\lib\distutils\cmd.py", line 333, in run_command self.distribution.run_command(command) File "L:\Python24\lib\distutils\dist.py", line 966, in run_command cmd_obj.run() File "L:\Python24\lib\distutils\command\build_ext.py", line 279, in run self.build_extensions() File "setup.py", line 117, in build_extensions build_ext.build_extensions(self) File "L:\Python24\lib\distutils\command\build_ext.py", line 402, in build_exte nsions self.check_extensions_list(self.extensions) File "L:\Python24\lib\distutils\command\build_ext.py", line 304, in check_exte nsions_list (ext_name, build_info) = ext TypeError: unpack non-sequence The only information I can find about this is an ongoing dispute about some Pyrex version causing this issue: http://mail.python.org/pipermail/distutils-sig/2007-September/008211.html I am using Python 2.4, NOT Pyrex. I am on Windows XP 2. Any help would be appreciated. Mike
