A couple years ago I had to compile it from source, but I now see that
it is a deb package. The package is what I installed. The package
description said it depended on libstdc++.so.6. However, to get it
started I had to install libstdc++.so.5.

  $ ldd /usr/bin/gmfsk | grep libstdc
        libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb738e000)

So, since I had libstsdc++.so.6 installed, and this is what it needs,
why would installation of libstdc++.so.5 enabled it to work?

Yep, both now installed:

$ ls -l /usr/lib/libstdc*
lrwxrwxrwx 1 root root     18 2008-04-07 06:14 
           /usr/lib/libstdc++.so.5 -> libstdc++.so.5.0.7
-rw-r--r-- 1 root root 737624 2007-01-03 13:47 
           /usr/lib/libstdc++.so.5.0.7 
lrwxrwxrwx 1 root root     18 2007-04-22 09:40 
           /usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.8
-rw-r--r-- 1 root root 909044 2006-12-10 09:45 
           /usr/lib/libstdc++.so.6.0.8

The logic of the situation seems almost as if gmfsk needed _both_
versions of the libstdc++ library.
