            Bug ID: 91385
           Summary: gallium xvmc tries to symlink non existing libraries
                    on OpenBSD
           Product: Mesa
           Version: git
          Hardware: Other
                OS: OpenBSD
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Other
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: jsg at openbsd.org
        QA Contact: mesa-dev at lists.freedesktop.org

The gallium xvmc Makefile assumes the system uses Linux style library names
with
libfoo.so.major.minor.revision with symlinks to libfoo.so.major.minor and
libfoo.so.major.

On OpenBSD libtool creates libfoo.so.major.minor even if revision is specified
and ld.so will find the appropriate library if libfoo.so or libfoo.so.major is
dlopen'd.

It seems the Makefile has already wrongly installed
libXvMCr600.so and libXvMCr600.so.1 into the prefix
and correctly installed libXvMCr600.so.1.0 when the error occurs.
