You could use the previous version of the platform, which was for 6.10.x.

Perhaps there's a 6.12.1 in debian unstable, IIRC, Ubuntu uses debian 
packages, so you could install that then.

Or you could build 6.12 from source.

Or that. Install just the packages you actually use. That worked before the 
platform, it will continue to work, though getting a comprehensive set of 
libraries is a bit more inconvenient.

If you build from source, you need a working GHC installed, so no.
Don't know about the binary, but usually there's no problem having multiple 
versions of GHC at once, so probably you don't need to uninstall anyway.
