Could not find sub !UNIT_OUTER

[a b]

Hi,

I have a little problem with compiling perl6 programs with rakudo-star-2010.07:

# cat test.p6
say "Greetings, earthlings, err Perl 6 neophytes.";

# perl6 test.p6
Greetings, earthlings, err Perl 6 neophytes.

# perl6 --target=pir test.p6 >> test.pir
# parrot prog.pir
error:imcc:syntax error, unexpected PREG, expecting '(' ('$P67')
        in file 'prog.pir' line 36
error:imcc:syntax error, unexpected PREG, expecting '(' ('$P69')
        in file 'prog.pir' line 40
error:imcc:syntax error, unexpected PREG, expecting '(' ('$P71')
        in file 'prog.pir' line 44
error:imcc:syntax error, unexpected PREG, expecting '(' ('$P1')
        in file 'prog.pir' line 64
error:imcc:syntax error ... somewhere
        in file 'prog.pir' line 103

# echo ".loadlib 'perl6_group'" > test.pir
# echo ".loadlib 'perl6_ops'" >> test.pir
# perl6 --target=pir test.p6 >> test.pir
# parrot prog.pir
Could not find sub !UNIT_OUTER
current instr.: '' pc 158 (prog.pir:81) (prog.p6:1)

Is it a known bug? ;) Why compiling a simple perl6 program is so dificult?
