I hope all is well.  It appears I ran the wrong fix_libtool_files.sh

I first ran fix_libtool_files.sh 4.4.5  (which was an older version)

I now ran fix_libtool_files.sh 4.5.1, which seems to have fixed it.

The upgrade was from 4.5.1-->4.5.1-r1   so I guess 4.5.1 is the old
version.

What confused me is that it is also the "new" version since as far as
gcc-config is concerned the -r1 "doesn't count".
That is now, with the machine working again,

ajglap x86_64-pc-linux-gnu # gcc-config -l
 [1] x86_64-pc-linux-gnu-4.5.1 *

which is what led me to believe that I needed an older version for
gcc-config.

I guess it is simply "user error" but it was scary.
So what is the right way to emerge a new gcc.  Is it

1.  do gcc-config -l to find the current active config
    and remember that version

2.  do the emerge with buildsyspkg feature

3.  run fix_libtool_files.sh with the version number from step 1.
    (even if it is the same as the current number from gcc-config).

Thanks.
