Eu estou tentando instalar o ming 0.4.2 do código-fonte e ele foi compilado antes no Ubuntu 10.04 , mas agora ele está dando os seguintes erros de compilação quando tento instalar usando o comando sudo make install ( libpng já está instalado).

A versão da libpng mudou entre o Ubuntu 10.04 e o 12.04. Você está usando uma versão antiga do ming - uma rápida olhada no changelog para a versão atual (0.4.4) mostra uma correção para versões mais novas do libpng.
Eu apenas tentei, e o ming 0.4.4 compila sem nenhum problema no Ubuntu 12.04.
