Fixed, and thanks for the find. Many are due to renaming tcz and tczl and factoring out libraries and typos. But GConf is using the version number in the extension name, which is against TC library extension policy.
I am going to seek out and ask the extension owners to rename any library extensions that are including the version number in the name and rename them since any update to them breaks the repo. Though end use apps that nothing else depends on - or special libs like openssl that is not compatible with apps across library upgrades and therefore need to be version specific - may have a version number in them, standard shared library extensions may not.
I will adjust the relevant dep files upon any renaming of extensions.
