Trying to figure out what exactly "gobjc" installs, I did:
sudo dpkg -L gobjc and got a path to /usr/share/doc/gobjc
Did : sudo apt-file list gobjc and got a path to /usr/share/doc/gobjc
on this directory you can only find text files that are .gz compress, I was expecting to find some .a, .o or any kind of file that actually process code as this package is used to compile objective-c code
