It wasn't an unusual filesystem (other than being within a logical
volume).  Nothing out of the ordinary -- a local /ext3 filesystem.  I
did a clean re-install of Fedora from scratch, and boom!  Postgres
compiled and installed just fine.

Two interesting tidits here (perhaps of note)  -- 1) Against my
judgment, I had been using Fedora's upgrade process the last two times I
updated (from F12 to F13, and from F13 to F14).  I wonder if that
botched something in my environment and 2) Nothing else on the system
seemed to have trouble (at least up until that point in time).   I
suspect it was definitely something underneath Postgres, as when I
deleted everything in /usr/local/pgsql and my cluster (/data/postgres)
and started anew, it still had the very same problem.  Just some
additional points of info.

In any case... a "clean" install of Fedora 14 did not yield this
problem, so feel free to close this issue if/when you feel appropriate.

Thanks to everyone that was lending assistance.  It's much appreciated.
