Try to rebuild media-libs/libpng package.

Thanks for the reply!
I have rebuilt libpng and ran revdep-rebuild, I still have the same error

It looks like you have a libpng.so in /usr/local/lib and probably this cause the error.

| As fedeliallalinea says, the build system is using /usr/local/lib/libpng.so to try to provide libpng.so. This file was installed outside of Portage and will not be rebuilt/upgraded by re-emerging the libpng package. This is probably not what you want. Since Portage will not touch that file, rebuilding the Gentoo package libpng won't help you. Removing the offending library from /usr/local/lib probably will. However, where there is one locally managed file, there are usually more. I suggest posting the output of find /usr/local/include /usr/local/lib* -type f -ls for review. In most cases, the correct output is to find no files (excepting ones named .keep, which exist to force the directory to be present; those are harmless). |

In addition to what Hu said remember that /usr/local takes precedence over what is installed in /usr.
That is why it is not recommended to install a package manually if is present in official tree.

| I did have some older versions of the library for a different application in there, I removed them and it works! Now everything makes senses thank you! |

If you need an older libpng version on runtime exists media-libs/libpng-compat in tree.
