 exiv2 0.27.3_0 fails to build with the following error:
 {{{

 Full build log is attached.

 The problem seems to be that exiv2 finds and links to system libiconv,
 which uses iconv prefix for exported symbols instead of libiconv. But
 libiconv installed by macports uses libiconv prefix and its header gets
 pulled into include path before system one it seems. I'm not sure how/why
 it worked before... When building manually this doesn't happen, so maybe
 new macports version (it got upgraded from 2.6.2 to 2.6.3) now force
 /opt/local/include into include path?..
