 I saw this too with some other packages, and I felt it was okay.
 These are due to a bug in pkg_admin because, for example, in your
 output above, the symlink:
 
     /usr/pkg/emul/netbsd32/usr/lib/libm387.so
 
 definitely exists on the filesystem.  It just happens that it's an
 "emul" symlink, which points to "/lib/libm387.so", which gets mapped
 to /usr/pkg/emul/netbsd/lib/libm387.so by the COMPAT_NETBSD32 emulation
 code.  Unfortunately, pkg_admin tries to verify the existence of the
 target of the symlink instead of the existence of the symlink itself,
 and when it doesn't see "/lib/libm387.so", which shouldn't exist on
 your amd64 system, it spouts that warning.
 
 We can do one of the following:
 
     (1) Leave the warning, which doesn't break anything.
     (2) Teach pkg_admin not to follow symlinks.
     (3) Ignore the output of pkg_admin.
 
 I would like to do (2), and maybe change that warning to say:
 
     pkg_admin: Target of symlink "/usr/pkg/emul/netbsd32/foo" may not exist.
 
 so that the warning doesn't sound quite so alarming.
 
        Thoughts?
