Hmm...  I see in /usr/share/doc/parrot-0.6.4/languages/perl6/README:

------------------------------8<------------------------------
If you want to create a binary executable of the compiler
that can be invoked as "perl6" from the command line, then
try "make perl6".  This will create a "perl6" (or "perl6.exe")
binary that can be directly used from the command line:

    $ ./perl6 hello.pl

This binary executable feature is still somewhat experimental,
and may not work on all platforms.  Also, the binary has hardcoded
paths to the Parrot build tree (especially the dynamic libraries
and modules), so removing the build tree will cause the binary
to stop working.
------------------------------>8------------------------------

... which sounds like a likely explanation.
