$ libpng-config --L_opts
-L/usr/lib64
$ libpng-config --R_opts
(none)

This is quite inconsistent, unnecessary and when applied with bug 487696, causes failures for multilib.

While I can agree there are other ways of solving this, IMO just dropping the -L flag would be the simplest one. That's what pkg-config does by default, for example.

if your package is still using libpng-config, it is broken.  i say use this as a marker for "i need to update to pkg-config".

I raised this issue:

https://github.com/pnggroup/libpng/issues/643

I've always found installing both to be confusing.
