Update:
- the re.bs and re.so files in /tmp seem to be a leftover from a Zope 2.7 installation
- when tried from /tmp as the current working directory, importing re fails:
<SNIP>
0 www:/tmp # python
Python 2.3.5 (#1, Apr 19 2005, 03:28:52)
[GCC 3.3.1 (SuSE Linux)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import re
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: ./re.so: undefined symbol: PL_dowarn
>>>
</SNIP>
  (inactively or non-interactively, with or without -O flag)
- no . nor /tmp entry whatsoever in $PATH environment variable
- of course, the error doesn't occur with both files deleted

Thus, somehow the /tmp directory must have become the working directory during import of the re module (with --optimize option only!)

No further idea then, sorry.

I tried /usr/local/bin/python -O -c "import re", I tried it interactively, I tried both users root (used during install) and zope -- no errors whatsoever.

Agreed.  The OP needs to figure out why Python is attempting to
open '/tmp/re.so' as a Python module;  that is what is causing
the problem.

If the OP doesn't need that file (it is in /tmp, after all),
then remove it and try again.

BTW, I was just able to build and install from the 2.7.6 source
tarball on both Ubuntu 5.04 and CentOS 3.

FWIW, you should check that you can indeed do "import re" from a Python prompt on your system when in "optimize mode". (e.g. $ /usr/local/bin/python -O -c "import re") without an error.  It appears from your traceback that the cause of the install failure is that this install of Python cannot import the re module, which is highly irregular.

I can't believe it! Please reopen!

Maybe someone else can, e.g. someone with SuSE Linux and Python 2.3.5 trying to install the standard Zope 2.7.6-final source package?

/I/ didn't do anything special to the re package.

Configuring Zope installation

  - Zope top-level binary directory will be /opt/Zope-2.7.
  - Distutils install flags will be "--optimize=1 --no-compile"
  - Makefile written.

  Next, run make.

$ make

Zope built. Next, do 'make install' (or 'make instance'
to run a Zope instance directly from the build directory).

$ make install
...
Zope binaries installed successfully.
Now run '/tmp/collector_1786/installed/bin/mkzopeinstance.py'

---------------8< ------------------------

I do see one odditiy in your environment: the traceback shows that
Python is trying to import an odd filename: '/tmp/re.so'.

The 're' module in Python is not a shared library, but a wrapper
around the 'pcre.so' library (in the 'lib-dynload' directory of
your Python library).

Specifying the --optimize flag with ./configure causes make install to fail:
