By-the-way, the folder is there on my Macbook Air, but it's empty. Seems the install created the folder, but did not populate it with the libraries. I haven't checked my big install on my iMac, but then I installed a XTools on it. . . so I expect it's got everything there.
Yes, I installed the “Xcode Command-line tools” at some point - that must have installed Perl there.
I also have an install of it over in /opt, since I use MacPorts to get a lot of standard-issue UNIX packages. (Using MacPorts versions is also good to never monkey with the versions of the standard UNIX tools that Apple depends on the exact behavior of. You can upgrade MacPorts versions of tools, Apple will upgrade their tools only when needed.)
I suppose we need to worry about installs going on there, as well.
In fit of ambition I installed XTools on my first iMac under an early version of OS X. Never did anything with it, and PROBABLY it’s not on my current sys since I’m pretty sure that, whereas XTools came free with that first iMac I would have had to have bought XTools for my later Mac, and I’m rather sure I didn’t do that.What would be an easy way to check that?
