Hello again, any of you has the experience in installing ZPattern? I would like to try Emarket product but it requires ZPattern. Then, I installed ZPattern but the error occured during import module as the following ..... File /home/pattreeya/Zope-2.3.0//lib/python/Products/ZPatterns/DataSkins.py, line 1, in ? ImportError: No module named DynPersist. I have checked and found that DynPersist is in c format. And no Makefile inside the product or whatever related to c file. I have check inside /lib/python to look for the config or Makefile but I found nothing save only one Makefile.pre.in in ZMySQLDA. The information from "Setup" in .../ZPatterns contains only *shared* DynPersist DynPersist.c -I../../ZODB -I../../../Components/ExtensionClass At this point, i have no idea what to do next. Currently, I use Zope2.3.0 and Zpatterns-0.4.3b1. Thank you in advance for any help. pattreeya.
