make sure you only have one version of the libraries and resp. dev files.
having some under /usr/local as probably built and from installed from source and another set under /usr as usual for system officially installed packages, is the most common route for the kind of troubles you're experiencing.
get rid of anything related to serd, sord, sratom, suil and lilv (ie. the complete drobilla's lad/lv2 stack, from both /usr and /usr/local and in this order) then try re-building and installing from the latest released sources.
smells like trouble with libsuil et al.
