Re: Can I install both GTK+2 and GTK+3?

[Gary Kline <kline thought org>]

        Hello people,

        Apologies if this is the wrong place to post my questions, but they
        involve Ubuntu 13.04 and GTK+ as well.  A few weeks ago I finished
        porting my program for the speech-impaired to Ubuntu 12.04 LTS. 
        This is intended for the OLPC project and also runs on Fedora.  Now
        that my program runs on 12.04 I figure it should work on 13.04 LTS
        without any mods.  

        In previous versions of Ubuntu, upgrading to the next LTS was 
        nothing more than a few mouse clicks but not now.  Does anybody on
        this gtk list who uses Ubuntu have any idea where I am messing
        up?  My other question involves porting my speech program to
        laptop.org.  Several other hackers have helped with the gtk code;
        it is mostly 3.x.  The nutshell is: should I just hand my 
        program to the sugar-devel folk and be willing to help with 
        what it needs {espeak, [g]vim, and whatever else} or what?

        thanks for any help,

        gary
