>Description:
devel/netcdf comes with a ${DESTDIR}/lib/libbzip2.so.

This .so is picked up (in my case directly in /usr/pkg/lib/libbzip2.so, not in the forest of symlinks) by the configure script of archivers/libzip but fortunately the build phase fails to link with it. It is clear from Makefile, bzip2/buildlink3.mk, and intuition that it is not this .so which is supposed to provide bzip2 support to libzip.

devel/netcdf should not provide this library and/or archivers/libzip should protect itself from detecting it. Sorry, I don't know how to make any of the two happen.

>How-To-Repeat:

(cd devel/netcdf && make install) && (cd archivers/libzip && make)

>Fix:
Unfortunately, no clean fix. I worked around it by building the packages in the other order.
