Multiple Errors trying to install GLScene

[edsquare]

Hi, I'm new to the forum, and I trully hope someone can help me:

I'm using LinuxMint 17 Qiana with Cinnamon desktop, Lazarus version is 1.2.6 and while trying to install GLScene I ran into different errors depending on what version of GLScene I'm trying to install.

Couldn't find anything helpful in the forum or even praying to saint google :-(

The errors are below together with the GLScene version that originated it.
