Comment (by dsedivec):

 Sorry to potentially move the goalposts, but I've now noticed a similar
 problem with libs and thought maybe I should bring it up here:

 {{{
 $ pkg-config --libs libxml-2.0
 -L/opt/local/lib -lxml2

 $ xml2-config --libs
 -L/opt/local/lib -lxml2 -L/opt/local/lib -lz -L/opt/local/lib -llzma
 -lpthread -liconv -L/opt/local/lib -licui18n -licuuc -licudata -lm
 }}}

 Note that xml2-config knows about the ICU libraries, but pkg-config
 doesn't.  (`--cflags` is same for both pkg-config and xml2-config.)

 This is making me wonder if I'm even supposed to be using pkg-config with
 libxml2?
