PL/Parrot definitely needs at least Parrot svn rev 45961, but running on the latest trunk is best, for now, until the embedding API is stable.
If you look in your Postgres logs, you will probably see something like:
error:imcc:syntax error, unexpected LOADLIB ('.loadlib') in file 'EVAL_1' line 1 src/extend.c:307: failed assertion 'sub_pmc'
I fixed this error in the latest master branch of PL/Parrot.
If you update, you may get a different error like:
ERROR: Error compiling PIR function: arg count mismatch: op #1119 'open' needs 420 given 3 STATEMENT: select isnt(test_open_plparrotu(), 42, 'open opcode is not mocked in plperlu');
This is the bug I am trying to get around in Parrot, or figure out how to not get bit by it.
If you have other problems or failures, feel free to sent the full output of

I installed the latest parrot from svn and git-pull'ed plparrot as you noted and got the same error as

Yes, this error is actually caused by a change in Parrot internals very recently, and currently means that PL/PIRU (with is the same thing as PL/ParrotU) does not work currently. I am working with Parrot devs to short the issue out soon.
The gory details: We rely on fiddling with the open opcode, which was just recently became a dynop (dynamicly loadable opcode.) A long-standing bug with dynops and bytecode was then tickled by this, which is where things went BORK.
Thanks again for your interest in PL/Parrot and let us know if you run into any other issues or have ideas for more features.

Just to clarify, PL/PIRU *does* work currently, but you cannot use the "open" opcode in it, you have to use the "open" method on the FileHandle object. So it is not a huge blocker, but the test suite does currently fail because of this.

Yeah, I see fundamentals working correctly in tests, though I've not looked deeply yet. I'll play with plparrot and later with perl6 on plparrot in a few days.

It is still very rough, but it attempts to load perl6.pbc and gets this error message:
Null PMC access in find_method('new_class') current instr.: '' pc -1 ((unknown file):-1) called from Sub 'perl6;Perl6;Compiler;main' pc 284183 ((unknown file):-1) ... call repeated 1 times
