`make distcheck` fails

[jhoblitt]

I'm not sure exactly what is triggering the failure but it's pretty likely that
there is a messed up path in one of the makefiles. I failed to reproduce the
error but doing my own our of tree build but this is still worrying.

"make distcheck" works for me now (apart from failing a psDB test). In
particular, the multiple psLibInit isn't a problem. The code has evolved
somewhat since this bug was filed.
