One of the issues that we need to resolve is the pre-compiling packages. It is very handy for trials, but on clean installs it is required to install dependencies such as pygame and gtksourceview.
Another issue that we are facing is a problem with 64bits. Icaro requires to install most libraries in 32 bits, ending with two version of each library.--Yn1v 20:00, 21 May 2012 (UTC)
