OS X Update Killed My Rails!

I thought this was a problem only associated with Microsoft updates! Apparently not!

If you compiled Ruby from source, following instructions from this Hivelogic tutorial, the latest OS X Tiger update may have killed your symbolic link to Ruby 1.8.4.

(This assumes you had installed Ruby 1.8.4 to /usr/local and had symbolically linked to this binary from /usr/bin/ruby)

Simple enough solution though:

cd /usr/bin
sudo mv ruby ruby.back
sudo ln -s /usr/local/bin/ruby /usr/bin/ruby

Now try a “ruby -v” and you should see 1.8.4 as the version.

(In defense of OS X — at least I’m not rebooting into 8bit, 16color 800×600 resolution on my 20″ flatscreen, as has happened w/ MS updates before.)
