Installing Non-Ruby Dennou Tools by MacPorts

1. Install MacPorts in your Mac.

2. Make a directory under your $HOME and check out the MacPorts-JP’s ports tree from its SVN repository.

$ mkdir ~/Sources
$ cd ~/Sources
$ svn checkout macports-jp-trunk

3. Edit “/opt/local/etc/macports/source.conf” as below. (add 4th line)

#  NOTE: The port command parses source URLs in order and installs the                                   
#        first occurrance when a port appears in multiple repositories.                                  
#        So keep "file://" URLs above other URL types.                                                   
file:///Users/Your User Name/Sources/macports-jp-trunk/dports

#  To get the ports tree from the master MacPorts server in California, USA use:                         
#      rsync://                                                         
#  To get it from the mirror in Trondheim, Norway use:                                                   
#      rsync://                                                  
#  A current list of mirrors is available at
rsync:// [default]

4. Execute

$ sudo port -d sync

5. Now, you can install Dennou Tools (C-DCL for example) by

$ sudo port install C-DCL6

Note that, most Dennou Tools depend on some large libraries (e.g., gtk2) which may take long time to compile and install.
