#25015 — select module missing/corrupt

We are using a virtual web server running some version of Unix. It has 
Python versions 2.4,2.6 and 3.1 pre-installed.

(BTW the intention is to use Python for a CGI script.)

When my script imports subprocess I get the traceback
   File "/usr/lib/python2.6/subprocess.py", line 427, in <module>
     import select
ImportError: No module named select

On searching the Python installation I found what I presume is the 
select module library file

/usr/lib/python2.6/lib-dynload/select_failed.so

whereas in the 2.4 installation the file is
/usr/lib/python2.4/lib-dynload/select.so
and subprocess imports OK.

Anyone know why the version 2.6 select .so file should be renamed 
select_failed.so and so not able to be imported?

Of interest the 3.1 installation also has the select module file 
re-named select_failed.so.

Any help appreciated,

Regards,
John Pote

When python builds, modules that don't build cleanly get renamed 
[module]_failed.  See 
http://mail.python.org/pipermail/python-dev/2002-March/020568.html for 
more info.
