Thank you. Fixed.

Seems like macports recommend to use xcode.destroot.settings
technique, and it seems failed. Is it macport bug then or latest xcode
breaks something?

It does it because 'file copy' points to a soft symlink (that what
build system create in output folder soft symlink to some output
folder). Seems like double job for a developer to check if it actual
folder or a symlink and run 'file copy' depend on what type of file is
that. May be we need help from macport build system to copy
symlink/folder command ?

  set from ${worksrcpath}/build/Release/${name}.prefPane
  set to ${destroot}/Library/PreferencePanes

copy(from, to) {
  if {[file type ${from}] == "link"} {
    file copy [file readlink ${from}] ${to}
  } else {
    file copy ${from} ${to}
 }
}
