This week in Seven Languages in Seven Weeks brings the Io Language. Installing the binaries is, of course, the first task in beginning to use the language. However, I’m not off to a roaring start just yet.
After installing the binaries using the Mac package installer, I find that the io binary is not found.
$ io
-bash: io: command not foundLet’s try this…
$ /usr/local/bin/io
bash: /usr/local/bin/io: Permission deniedHmmm… it is there, but I can’t access it… let’s look closer.
$ ls -l /usr/local
total 0
drwx------ 17 macports wheel 578 Aug 18 11:08 binWell, that explains it. For some reason, MacPorts set up /usr/local/bin/ with very restrictive permissions. And, apparently, I’m not the only one to run into this problem:

- http://echelog.com/logs/browse/macports/1335477600 (search for [03:31:09])
Let’s fix it with chmod.
chmod a+x /usr/local/bin/It works!
$ io
Io 20110905

Now, on to the fun stuff…
