I've been playing with pyblosxom locally and with my hosted account. It's a while since I did much .cgi, so "premature end of script headers" in the apache error.log was confusing again. Of course it really seems to mean "some of your file permissions are wrong". I don't think I've been aware of suexec before, though it's probably quite common. Dreamhost use suexec, so you'll get that error if the .cgi script is writable by all. It's about time something stopped me from trying to fix permissions problems by giving full access to everything.
pyblosxom is nice and simple - you just put text files in a directory of your choosing, and it uses the date of the file on the filesystem to assign that entry to a date on your blog. Obviously, having to put files in there directly using a ssh session is impractical, so there is a primitive weblog-add.py script that lets you do it over the web, using apache's regular .htaccess user/password thing to restrict access. It's kind of annoying that I have to think of a filename manually, but that's not the end of the world. Also, the page-layout template system seems quite simple, with no embedded code.
I did look a the WordPress online demo, and it looks a lot more user-friendly. But I'd like to avoid maintaining a MySQL database just for my blog. I'm marginally more familiar with python than PHP, so the appearance of PHP in their templates alarms me. Also, I keep hearing about PHP being somehow fundamentally problematic for security, though I don't have the slightest idea of why.
So I am trying to get the pyblosxom xmlrpc interface to work, so I can use friendlier tools to post blog entries. I notice that the xmlrpc plugin needs python 2.2 rather than 2.1 - I think that's what the "NameError: name 'True' is not defined" error is about. So I changed the top of the pyconfig.cgi script from "#!/usr/bin/env python" to "#!/usr/bin/env python2.2". I'm not sure if that is the right way to do it. Also, python 2.2 seems to come with xmlrpclib, but you have to download xmlrpclib and copy it somewhere manually if you are using python 2.1.
It looks like gnome-blog is not quite up to date with recent pyblosxom. When using the "Self-Run Pybloxsom" Blog Type, it tries to access an xmlrpc.cgi script, but there's none in the pyblosxom-0.9.1 tarball. When I try to use the "Self-Run Other" Blog Type with The "BloggerAPI" or "MetaWeblog" Blog Protocols, givint if the URL of my pyblosxom.cgi script, it reports an "internal server error" and I get this in my error.log file.
Traceback (most recent call last):

But I feel that I've done quite well, and I'm sure somebody will email me with a helpful clue.
