Details
Not a big deal, but I notice that when I moved my tree and blew away my $bld directory, builds still broke because the srcdir contains a stale ipdl_yacctab that contains the old pathname.
Should we be generating then deleting these files instead of leaving them lying around?
This isn't really IPDL's fault; it's the PLY parser that generates and manages these. We could just disable the tables, but this would slow down parsing a bit. Probably not a big overhead.

It turns out deleting the ipdl_yacctab.py file is not enough to build after a srcdir move. You also need to delete all the *.pyc files in ipc/ipdl, as python has "cleverly" precompiled the .py files in such a way that they remember their pathname without bothering to check whether it's changed, and we're somehow using that info to search for files that are no longer there. "rm *.pyc" fixes the issue.
I've always thought Python was overrated. Too bad about Perl 6.

We can tell PLY where to put the generated files, the same way we do for qsgen.
