As you can see from the logs, the package was autobuilt, so that is not the
case.

Just a disclaimer: I'm not a maintainer of the package, and I'm really not
gonna try pbuilder.
Probably: The logs are more than a week old by now, and I don't know if the
dependencies were really satisfiable at that point. However, it's hard to
imagine a situation where libglib2.0-0 (2.15.5-1) is available but
libglib2.0-dev (2.15.5-1) is not.

Sorry, but this explanation is bogus. See:
debian:/usr/src/linux-2.6.23.9# apt-get install -d libglib2.0-dev
libglib2.0-0=2.15.6-1

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
libglib2.0-dev: Depends: libglib2.0-0 (= 2.14.6-1) but 2.15.6-1 is to be
installed
E: Broken packages
But, at the same time:
debian:/usr/src/linux-2.6.23.9# aptitude install -d libglib2.0-dev
libglib2.0-0=2.15.6-1
Reading package lists... Done
Building dependency tree
Reading state information... Done
Reading extended state information
Initializing package states... Done
Building tag database... Done
The following packages are BROKEN:
libglib2.0-dev
The following packages have been kept back:
... snip ...
The following packages have unmet dependencies:
libglib2.0-dev: Depends: libglib2.0-0 (= 2.14.6-1) but 2.15.6-1 is to be
installed.
Resolving dependencies...
The following actions will resolve these dependencies:
Upgrade the following packages:
libglib2.0-dev [2.14.0-2 (now) -> 2.15.6-1 (experimental)]
Score is -9980
Accept this solution? [Y/n/q/?] q
So apt-get failed where aptitude found a (straightforward) solution in a
situation, which seems to be quite similar to what is in the logs.
