I don't see the problem here. TagLib is a hard dependency of the plugin and its header files are obviously missing. I wonder why the configure script doesn't raise errors, though. It already checks for taglib/tag_c.h and aborts if that isn't found.
Hmmm, I had libtag1-dev installed but just did an apt-cache search anyway and discovered there is also a libtagc0-dev. Anyway, I installed that and it solved the problem. <sigh> sorry for the excess noise :-(
Hm, yeah, actually tag_c is the dependency. I still wonder why it's skipped in configure.
