Thank you, Duncan, for the explanation and suggestion.

Doing "fix_libtool_files.sh 4.2.0" or "fix_libtool_files.sh 4.2"
elicited the following response:

* Scanning libtool files for hardcoded gcc library paths...
gcc-config: error: could not run/locate 'gcc'
:0: assertion failed: (gcc -dumpversion) | getline NEWVER)

To check what newer version is installed, I did "emerge --search gcc".
The response included the following lines:

Doing "emerge --empty-tree world" evoked the following response:
emerge: error: no such option: --empty-tree

Trying to check the available options, I did "man emerge" but just got
groff: /lib/libgcc_s.so.1: version `GCC_4.2.0' not found (required by
/usr/lib/gcc/x86_64-pc-linux-gnu/4.3.2/libstdc++.so.6)

It looks as if the problem affecting Firefox and Thunderbird also
affects man.

I'd be very grateful for suggestions about what to try next.
