Initial support for Panther

[larb0b]

This adds initial support for Panther.

One would be able to curl -fsSkL raw.github.com/mistydemeo/tigerbrew/go/install_panther | sudo sh - and tigerbrew should be installed.

Further than just installing tigerbrew, install_panther installs tar 1.15 into /usr/local (tar builtin to Panther doesn't support --strip) and ruby 1.8.5 into /System/Library/Frameworks/Ruby.framework/Versions/Current (Panther has no Ruby in there by default at all, but tigerbrew shebangs scripts with that Ruby in numerous places). It also creates a symlink from /System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby to /usr/local/bin/ruby.

Note that even with this brew still seems to want to use /usr/bin/ruby at least when it's initially run.

I'm now able to get as far as

/usr/local/bin/brew: line 219:  7906 Trace/BPT trap          "./$VENDOR_VERSION/bin/$VENDOR_NAME" --version >/dev/null 2>&1
Error: Failed to install vendor ruby.
Error: Failed to install vendor Ruby.

if I symlink /usr/local/bin/ruby to /usr/bin/ruby.

This is amazing, thank you! 🙌🏻

The vendor Ruby is built for Tiger, so I'm not surprised it doesn't run on Panther. We might have to build a new Ruby just for Panther in order to get something that runs.

There might be a few shebangs that need work to ensure everything runs using the vendored Ruby. This wasn't a huge issue on Tigerbrew because a lot of the most basic code has been written to support 1.8.2, but I think that stuff should get fixed up for sure.

Yeah, I only took a cursory look at everything (I'm still not entirely sure how brew picks which ruby it's using before vendor Ruby installed), but it seems most things (at least in ENV) use /System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby.

Maybe we could just have this install script to just install a Ruby as vendor Ruby for brew as a lazy hack?

What version of Ruby would you want minimum for the vendor Ruby? There were some errors when I tried to build 2.7.1 (and it also requires that you build a newer GNU Make), but I'm sure they could be patched around if needed.

I tried doing it with 1.8.5 (https://github.com/larb0b/tigerbrew/blob/13cee23be41de95dd3278fc319199b0fb425fb33/Library/Homebrew/cmd/vendor-install.sh) but

$ brew
Error: Failed to install vendor ruby.
Error: Failed to install vendor Ruby.

it'd be nice to get more verbosity out of this!

By the way, I can supply SSH access to a Panther machine if any contributors would like to help.

This workaround works to get it around trying to install a vendor Ruby but 1.8.5 is too old to work for brew. There are numerous errors when compiling later versions on Panther, however.

We're currently using Ruby 2.3, though I'll be upgrading later. What were the errors?

That'd be amazing! I currently don't have any hardware able to run Panther that could work on this.

[larb0b]

I don't remember what the errors were and I don't think I have them saved anywhere, but I might try to reproduce my progress at some point.

I've set up a 1.33 GHz iBook G4 w/ the latest OpenSSH, if you send a key my way then I can provide access.
