gnome-power-manager fails to build

[Eduardo Cerejo]

Trying to build this port on FreeBSD 7.1 release but it fails either using just make or portupgrade, I cvsuped my ports twice in the last two days to no avail.

file=`echo tr | sed 's,.*/,,'`.gmo \
          && rm -f $file && /usr/local/bin/msgfmt -o $file tr.po
file=`echo uk | sed 's,.*/,,'`.gmo \
          && rm -f $file && /usr/local/bin/msgfmt -o $file uk.po
file=`echo vi | sed 's,.*/,,'`.gmo \
          && rm -f $file && /usr/local/bin/msgfmt -o $file vi.po
file=`echo zh_CN | sed 's,.*/,,'`.gmo \
          && rm -f $file && /usr/local/bin/msgfmt -o $file zh_CN.po
file=`echo zh_HK | sed 's,.*/,,'`.gmo \
          && rm -f $file && /usr/local/bin/msgfmt -o $file zh_HK.po
file=`echo zh_TW | sed 's,.*/,,'`.gmo \
          && rm -f $file && /usr/local/bin/msgfmt -o $file zh_TW.po

Any idea what might be causing this?
