I'd say you're well qualified.
As with most porting jobs, you don't have to understand
the internal algorithms. It's better that you understand the
C compiler, and the available C libraries and include files.

As I recall, I had the interpreter running in about 3 days,
working 2-3 hours per day on it. I started compiling the source
as if it were a Linux system. I had to #ifdef-out
the GPM mouse stuff, because that library didn't exist.
I also had to remove an assumption that I made about how
malloc() works internally. I added #define BSD statements
in a just a handful of places where I had to do something
different from the Linux version.
Later I ported the Translator even easier than the Interpreter.
A few keys in ed.ex had to be reassigned for telnet.
Obviously, I wouldn't expect someone else to do a port
as easily as this, but the fact that two UNIX-based systems
have been done, means it shouldn't be too hard to do more.
I'm not sure if Sun supports ncurses, but I think they have curses.
There could be some work to do there.

I think you'll start off assuming that you're on
a "BSD" system (Sun Unix is closer to BSD than to Linux isn't it?).
You can use the batch file for building Euphoria on BSD.
It assumes GNU C and defines the "BSD" symbol.
You should add: #ifdef SUN (or whatever)
in places where you have to make a change.
I don't think there will be more than 10 or so places,
unless the curses incompatibility causes a problem.
If you get stuck, let me know.
I don't mind helping, but I'm concentrating
on the existing 4 platforms right now. I'm not ready
to fully take on another one.
