Comment (by kiwiroy):

 Please see report at https://github.com/Perl5-Alien/Alien-
 Libxml2/issues/13

 Alien::Libxml2 detects system libxml2 (macports provided here), but the
 tests fail for the reason Ray mentions.

 As a fix locally I’ve modified the last line of libxml-2.0.pc to read.
 {{{
 Cflags: -I${includedir}/libxml2 -I${includedir}
 }}}

 I assume ports that depend port:libxml2 aren’t affected as they have
 includedir (/opt/local/include) in CFLAGS anyway.
