I'm having problems using Eagle PCB version 5.12 in 64bit saucy. It seems to be a problem of libpng12-0.

eagle
eagle: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory



As the ia32lib stuff is gone, how do I get this satisfied? I do have the 64bit version of this library, but that doesnt' seem usable by Eagle. As there is not an apt package for Eagle 5, dependencies are not automatically satisfied.

ls /usr/lib/x86_64-linux-gnu/libpng*

/usr/lib/x86_64-linux-gnu/libpng*
/usr/lib/x86_64-linux-gnu/libpng12.a /usr/lib/x86_64-linux-gnu/libpng.a
/usr/lib/x86_64-linux-gnu/libpng12.so /usr/lib/x86_64-linux-gnu/libpng.so
/usr/lib/x86_64-linux-gnu/libpng12.so.0



I am able to use Eagle 6.5, having installed the apt package for eagle 6.4 to get dependencies, then removed the 6.4 version.

But there are times I want/need to use 5.x still, and so need this 32bit library somehow.
