Using Apple's GCC and MacPort's gstreamer:

$ gcc -v
Using built-in specs.
Target: i686-apple-darwin8
Configured with: /private/var/tmp/gcc/gcc-5367.obj~1/src/configure

--build=powerpc-apple-darwin8 --with-arch=nocona --with-tune=generic

Thread model: posix
gcc version 4.0.1 (Apple Computer, Inc. build 5367)

building fails with the following:

If I add "-multiply_defined suppress" to LDFLAGS, building fails with the
following:

I assume a "./configure && make" would suffice to build most libraries, but
that doesn't seem to be the case here. I'm not entirely sure if it's an error
in gst-python, or an error in how I'm building gst-python.

In any case, I'll attach logs for "./configure" and "make", for both with and
without using "-multiply_defined suppress"

Also, this is with gst-python-0.10.7, but the exact same errors occur with the
version in CVS -- if I let it build despite compiler warnings, that is.
