 While trying to upgrade all the outdated packages in my Power Mac G5
 running Mac OS X 10.5.8 Leopard, I wasn't able to proceed due to a build
 error in the `glib2` package. Since this is quite an important package I'm
 a bit worried. I've also attached the build logs, but the crucial part is
 this:

 I was able to find a related ticket:53150, which led me to do the
 following operation in order to try and fix this:

 {{{

 }}}

 What would be the next steps in order to resolve this issue?
