Confused about double libstdc++ depends

[Dirk Eddelbuettel <edd@debian.org>]

I just got

E: octave2.1: package-depends-on-multiple-libstdc-versions libstdc++2.10-glibc2.2 libstdc++5
N:
N:   The package seems to declare several relations to a libstdc version.
N:   This is not only sloppy but in the case of libraries, it may well
N:   break the runtime execution of programs.
N:

but the program does indeed run fine.

Do I need to worry about the error?  Octave now builds with gcc/g++ 3.2 as it
needs some STL functionality absent in 2.95/3.0.

Please CC me on replies.
