So the "internal" cppunit was probably not needed in the environment where the
"external" cppunit was also built with gcc46. But I guess that there is no
good way to detect that.
P.S. A hackish way would be to use something like objdump to check for
required versions of GLIBCXX in libcppunit*.so. But that's too hackish and
too much trouble, I guess.
But, hm, it looks like libcppunit-1.12.so doesn't require any newer symbols
from libstdc++ beyond what's provided by base gcc's library:
$ objdump -p -w /usr/local/lib/libcppunit-1.12.so.1
