Comment (by t.tensi@…):

 Dear all,

 in the course of the upgrade to icu 53.1 (defect #43959) there have been
 some additional changes in the port file like "enable-rpath".  I assume
 the changer has an OSX version after 10.5 and wanted to optimize some
 things, but it seems that those changes are not really necessary to build
 icu 53.1.

 Maybe the port file can be enhanced to check for Tiger and then leave out
 the rpath stuff.

 Best regards,
 Thomas
