Comment(by jkeenan):
Replying to [ticket:865 cotto]:
I started to look into this issue this weekend and committed some updates
to ''config/auto/pmc.pm'' and its associated test file which may help to
clear away the underbrush impeding a solution.
My hunch is that the problem is rooted in the fact that the only quasi-
canonical list of PMCs apart from ''MANIFEST'' is found in
''src/pmc/pmc.num''. That file provides a mapping of PMCs to incremental
sequence numbers (but also includes mappings for long-since-deleted PMCs.
If you call `touch src/pmc/myphony.pmc`, you will vary quickly get
uninitialized value warnings and outright failures during `perl
Configure.pl`. But I suspect that if have a well-formed PMC file there
which is listed neither in ''src/pmc/pmc.num'' nor ''MANIFEST'', it could
sneak into a Parrot build.
