octave-2.9.7 on OS X 10.4.7, and I'm getting the same error.

Just for the nth time:
This error is caused by trying to mix objects built with gcc3 and objects built with gcc4.

It usually comes up building mixed Fortran and C. If you use g77 for the Fortran, you must have gcc3.3 as the default compiler. (selected with gcc_select). If you use gfortran then gcc4 must be the default.

You can also get into this strife if you download a binary containing a static library, because there is no way I know to easily tell which compiler was used for the library. Either use dylibs, which are not compiler specific or build everything from source with a compatible compiler combination.

Don't stuff about with symlinks as advocated in lots of messages in the archives. That is all done automagically if you have the right default compiler. Fudging the symlinks might let something build, but it is likely to crash in a weird way while being run.

g95 is probably better avoided. It is now no better than gfortran in what it will build and to all account the resulting code on Darwin is generally not as fast at runtime.
