First pb solved: I had both python installed, original with libs in /usr/lib/python1.5 and 1.5.2 with libs in /usr/local/lib/python1.5 Removing the old one and setting the 1.5.2 to /usr solve Zope building pb. Now next problem: when I start Zope ./start I get: ------ 2079-10-04T14:46:29 PROBLEM(100) ZServer Computing default hostname Traceback (innermost last): File "/home/gilles/install/Zope-2.0.1-src/z2.py", line 430, in ? logger_object=lg) File "/home/gilles/install/Zope-2.0.1-src/ZServer/medusa/http_server.py", line 542, in __init__ ip = socket.gethostbyname (socket.gethostname()) socket.error: host not found I have a stand alone version of medusa, when it starts, the http chanel see my host name incorectly, the ftp channel is ok. It's probably somewhere in the doc/faq/mailing list. Unfortunatly I havent't find the solution until now. Any idee?? Thanks Gilles
