Finally found a solution. Module lxadmin is not registered, because initialization file __init__.py is missed in /usr/lib/python2.6/site-packages/lxadmin/ . Just create emty file __init__.py in this directory. I gonna post PKGBUILD into AUR archlinux repository.
Well, I installed gnome-common package (it contains gnome-autogen.sh script) and built lxadmin using this script. It still don't want to work, the same mistake:[vdr@archvdr ttt]$ lxccTraceback (most recent call last):File "/usr/bin/lxcc", line 22, in <module>import lxadmin.defs as defsImportError: No module named lxadmin.defsIt cannot find and load /usr/lib/python2.6/site-packages/lxadmin/ , dunno why. Why module is not registered by python?2010/6/28 Marty Jack <firstname.lastname@example.org>People: The repository and the tarball should include some autogen.sh that can turn a git repository into something that has a ./configure that builds a Makefile where make; make install works. It cannot be the case that you have to get an autogen from somewhere else to do this. We have a standard one that we use in the other packages. If necessary for this case it can be modified as needed to work.
