We are seeing a problem on the build cluster of the following form:

**tar: Pathname cannot be converted from UTF-8 to current locale.**

This is believed to be a problem only for ports being built under emulation (e.g. armv6, mips64).

At this time the errors are known to include:
  * audio/denemo
  * lang/yap-devel
  * textproc/es-hunspell
  * textproc/es-hypen
