I dislike that change. Setting LD_RUN_PATH is the jobs of whoever is
building the compiler, and should not be done by Python
automatically. So far, the Python build process avoids adding any -R
linker options, since it requires quite some insight into the specific
installation to determine whether usage of that option is the right
If setup.py fails to build an extension correctly, it is the
adminstrator's job to specify a correct build procedure in
Modules/Setup. For that reason, I rather recommend to remove the magic
that setup.py looks in /usr/local/Berkeley*, instead of adding more
