I just tried to install hobix and I got the following error when 
creating a weblog named 'test' in '~/test-hobix', during the end of the 
installation started with ruby -ropen-uri -e 
'eval(open("http://go.hobix.com/").read)':
-e:1: /sw/lib/ruby/1.9/fileutils.rb:467:in `mkdir': No such file or

After some checking, I got a directory '~' created where I started the 
program :oP
It contains just an empty directory called test-hobix. I guess it did 
not like directory names with '~' in them... I do not know if you can 
correct it, but I may not be the only one to enter a directory name 
staring with '~'.
When I created a blog with the following command, there was no problem: 
hobix create test ~/test-hobix

An other comment: Does it work with webrick? The installation mentions 
apache, but does it require it?
