Description of problem:
the spec contains a mistake in the configure options. The right option to compile ufraw with lensfun is "--with-lensfun", not "--enable-lensfun"
Version-Release number of selected component (if applicable):
it is impossible to compile ufraw with lensfun support
use lensfun library to correct lens defects.
Hmm, this really means UFRaw hasn't been tested with lensfun so far. I'll change it in devel CVS and rebuild the package on Rawhide, but won't enable lensfun in F-11 or earlier because it's not tested there and it really shouldn't be without enough testing, see: http://ufraw.sourceforge.net/lensfun.html
