>Description:
When libvpx is compiled on Mac OS (and possibly other systems), the rpath is 
set to the pkgsrc work destdir, causing the following to happen when a program 
linked to it is used

Martin-Brandenburgs-MacBook-Pro:~ martin$ ffmpeg
dyld: Library not loaded: 
/usr/pkgsrc/multimedia/libvpx/work/.destdir/usr/pkg/lib/libvpx.0.dylib
  Referenced from: /usr/pkg/bin/ffmpeg
  Reason: image not found
Trace/BPT trap

Here are the libraries used by /usr/pkg/lib/libvpx.0.dylib
Martin-Brandenburgs-MacBook-Pro:lib martin$ otool -L libvpx.0.dylib 
libvpx.0.dylib:
        /usr/pkgsrc/multimedia/libvpx/work/.destdir/usr/pkg/lib/libvpx.0.dylib 
(compatibility version 10.0.0, current version 10.6.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current 
version 125.2.0)

Not cleaning the libvpx directories causes the workdir to stay and the 
program/library to work.

However, the copy of the library produced by libvpx's buildscripts shows:

Martin-Brandenburgs-MacBook-Pro:libvpx martin$ sudo otool -L 
work/libvpx-v0.9.6/.libs/libvpx.0.dylib
work/libvpx-v0.9.6/.libs/libvpx.0.dylib:
        /usr/pkg/lib/libvpx.0.dylib (compatibility version 10.0.0, current 
version 10.6.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current 
version 125.2.0)

After bmake install:

Martin-Brandenburgs-MacBook-Pro:libvpx martin$ sudo otool -L 
work/.destdir/usr/pkg/lib/libvpx.0.dylib 
work/.destdir/usr/pkg/lib/libvpx.0.dylib:
        /usr/pkgsrc/multimedia/libvpx/work/.destdir/usr/pkg/lib/libvpx.0.dylib 
(compatibility version 10.0.0, current version 10.6.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current 
version 125.2.0)

In case this is also useful, here is the output of bmake install:

Martin-Brandenburgs-MacBook-Pro:libvpx martin$ sudo bmake install

----------------------------------------------------------------------
Libraries have been installed in:
   /usr/pkgsrc/multimedia/libvpx/work/.destdir/usr/pkg/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `DYLD_LIBRARY_PATH' environment variable
     during execution

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
