 Hello,

 I have an issue when making an app bundle for a opencv/python app with
 py2app.

 The py2app maintainer said:

 Shared libraries on OSX contain an absolute path to their location, and
 likewise all used libraries are also mentioned using an absolute path.
 Py2app uses macholib to rewrite those mentions to relative paths starting
 with '@executable_path'. For libraries that are located in /opt/local the
 new path requires more space than the old one, hence the error message.
 One way to ensure that there is enough space is the linker flag
 "headerpad_max_install_names". I don't know how to tell darwinports to add
 this flag when building opencv.

 I don't know either. Does anybody can help me to fix this issue?

 Best
