versioning problems with apt-get build-dep sylpheed
Hi all,
running "apt-get build-dep sylpheed" I see some problems on libgtk2.0-dev saying that libpango1.0-dev and libcairo2-dev are not going to be installed.
Trying to apt-get install them manually I have another message saying "libcairo2 (=1.10.2-6.1ubuntu3) but version 1.10.2-6.1ubuntu3+12.04ac1 is going to be installed".
Actually it's already installed.
I quite newbie in Linux programming and I don't know how to properly run "apt-get build-dep sylpheed" command.
Is there a way to override "strange" versioning number by ubuntu?
Thank you.
I think I've solved... by using synaptic to install libcairo2-dev, a few dependencies have been ported to older versions and I'm now able to instal build-dep for sylpheed!
I was unable to fix this by manually installing libcairo2-dev. I've even tried it from the live USB. Is there another fix for this?
Trisquel 6.0.1
Can't install libgtk2.0-dev

The following information may help to resolve the situation:

I finally managed to fix this as well using Synaptic, but it was tricky. I had to try to install libcairo2-dev, get an error message. Then I clicked "Mark all upgrades" which included DOWNGRADING libcairo2. After that I was able to install libcairo2-dev and libgtk2.0-dev
Thank goodness! Because I couldn't compile many apps without GTK 2.0
It did not work for me, I will install gnewsense on an external hard disk and build the packages there.
