Does Irrlicht for Irix still exist?

[Devil Master]

I've recently become curious about MIPS-based SGI hardware and I'm planning to buy an Octane to see what it can do (and eventually exhibit it at retrocomputing events). This page lists Irix among the Unix systems Irrlicht exists for, but I've never seen any Irix-related downloads. This is why I'm asking: does Irrlicht for Irix still exist, and how do I obtain it? If there are no binary blobs, is it as simple as compiling the source on an Irix machine?

Google says the card supports OpenGL 1.2, so yes, latest irr should run from source. Of course the other bits might have rotted, with nobody using such a machine in a long time, and to add insult to injury it's also big-endian. So trouble ahead, maybe not too much if you've done things like that before.

I've dealt with machines with different endianness, but for a much smaller project (porting a PLC program interpreter from one kind of CPU to another).
Anyway, Wikipedia confirms that VPro cards support up to OpenGL 1.2, but I've asked the same question in the Nekochan forum (about SGI machines)and they replied that Irrlicht requires OpenGL 1.5. Your reply, on the other hand, implies it doesn't, so I need to insist and ask: what is the correct information?

EDIT:
The Quake3Map.exe demo says OpenGL 1.5. So, this means no Irrlicht for Irix, right?

EDIT #2:
A user on the Nekochan forum has this to say about endianness and OpenGL versions:

Interesting. 1.4.2, at least, does run the Quake3Map demo on 10.4 on my Power Mac G5. This is noteworthy because not only is Mac PowerPC also big endian, but Tiger is only OpenGL 1.2. So I think it may work just fine on Irix.

Various features may get disabled on lower GL versions, but basic rendering should still work.

Is there a list anywhere of the features that would be disabled, ordered by version?

Irix is not officially supported by us. We don't have any test-hardware or programmers to work on it. But if you compile it and run into problems which we can solve easily we probably will do that. In the past one of our developers cared about Solaris, but he hasn't been active in a while. So at the moment Linux is the only Unix OS which we test.

Not really, nobody pretty much cares for such ancient cards. You can get a close approximation from looking at the opengl wikipedia page, what was added in each version.
