2.6.19. I am having errors using yum to update xmllib2, there are conflicts. This is going to be a big problem... WebService::YouTube seems like a great way to get what i wanted too.
Compile your own version of the libxml2 shared library and stick it in some useful library path... or just switch to Debian or Ubuntu ;)
yum was an admirable attempt to emulated Debian's apt system, but the service as a whole suffers from inconsistent levels of quality in package management and co-ordination (especially with respect to multiple versions of the same library).
