Thanks, Antoine.

And I think I just found the problem with the installation (it may be
worth a note):  I had  a special configuration file
(/usr/local/share/config.site) for autoconf to force the primary local
libraries to be installed in /usr/local/lib64 (left over from early
64-bit days of this old system).  Removing that file, removing the
/usr/local/lib64/python2.7 directory, and rebuilding and reinstalling
seems to have solved the immediate problem.

Moral of the story: watch out for old cruft in /usr/local when
installing a new distribution.

I apologize for the noise.

However, I'm still investigating the original build problem (gcc trunk
and corrupted byte compile), but it may be related--I'll see.
