I had to make a couple of minor edits to the files: "anyop.c" and "imcc.y" under the "languages/imcc" path --- the version was hardcoded with 0,0,7 but needs to be changed to 0,0,8 once in each file. I found mention of this on the perl6-internals list. After that, make test in the perl6 directory succeeded on all tests. I just wanted to point that out and possibly save someone a little grief. Time to write some Perl6 code I guess :-)
