Thank for your attention.

I try it:
suzc@linux-opensuse:22:02:51:Python-2.7.3$ PYTHONPATH=/WORK/suzc/installed/python/lib/python2.7 ./python -c 'import sys; print(sys.path)'

And I read the log of make, it seems to be compiled OK:

_struct.o and _struct.so are just there, I truely don't know what's wrong.
Newly to Python, I think python should not have such an installation problem.



I installed it(2.7.3) on RHEL5, works OK, but I want to install OpenSSL to it, don't know how to do it, so I learn to install it on SUSE in my workplace while RHEL5 is in another place. 

RHEL5 has python 2.4.2, in my memory. SUSE12 has python 2.7.2.

Does system's python affect my installtion? But I think it shouldn't.



In fact, long before I downloaded a compressed package named Python-2.7.3.tar.bz2, with this one, I can make && make install, but I can't run it, error is:

suzc@linux-opensuse:22:12:31:bin$ ./python2.7

I'm crazy about this, I search it in google, no satisfatory answers. So I want to download a new one 2.7.3, and install, but i just can not install it.

Thanks again.
