Further investigation has revealed the real cause of the problem
(I think):

This is not related to tar or zip, it's related to running the
setup.py script twice within the same extracted source archive.

The first time runs through fine, the second time you get the
error. This appears to be related to the build pickle that we
use to save build information between runs:

First run (without error):

running mx_autoconf
checking for availability of strptime()
gcc -fno-strict-aliasing -g -O3 -Wall -Wstrict-prototypes -D_GNU_SOURCE=1
-I/usr/local/python-2.6-ucs2/include -c _configtest.c -o _configtest.o
gcc _configtest.o -L/usr/local/python-2.6-ucs2/lib -o _configtest
success!
removing: _configtest.c _configtest.o _configtest
checking compiler for bad static forward handling
gcc -fno-strict-aliasing -g -O3 -Wall -Wstrict-prototypes -D_GNU_SOURCE=1
-I/usr/local/python-2.6-ucs2/include/python2.6 -I/usr/local/python-2.6-ucs2/include -c _configtest.c
-o _configtest.o
success!
removing: _configtest.c _configtest.o
enabling mx debug support
macros to define: [('HAVE_STRPTIME', '1'), ('MAL_DEBUG', None)]
macros to undefine: []
no build data file 'build/build-py2.6_ucs2.pck' found

Second run (with error and using the build pickle created by the
first run):

running mx_autoconf
checking for availability of strptime()
gcc -fno-strict-aliasing -g -O3 -Wall -Wstrict-prototypes -D_GNU_SOURCE=1
-I/usr/local/python-2.6-ucs2/include -c _configtest.c -o _configtest.o

FWIW, this appears to be fixed in a later version of mxSetup.py which is
included in the latest snapshot of egenix-mx-base:
