I've been using Gutenprint as the driver for my Epson 1160 ever since moving to OSX years ago. So I was happy to see the 5.2.2 update had gone golden. But once I installed it I was unhappy to find that it removed the contents of /usr/local/bin which is where the CUPS elements reside. I could no longer print to the 1160, until I downgraded back to Gp 5.0.2. I then tried upgrading to 5.22 again, keeping the /usr/local/bin window open; and sure enough the install process removed the elements again. This time I had first backed them up, and I was able to install them manually.

It was the Gutenprint Utility for Epson Inkjet Printers (which I used to print nozzel checks) that alerted me to the location of the missing files; other wise I wouldn't have had a clue where to look for them.

I'm pretty sure these file are not supposed to be removed, or that they should have been replaced with something newer.
