This has been in my upgrade queue for a couple of days now: it seems to hang here.

if ! test -d bg/; then mkdir bg/; fi

if [ -f "C/zenity.xml" ]; then d="../"; else d="/opt/local/var/db/dports/build/_opt_local_var_db_dports_sources_rsync.rsync.darwinports.org_dpupdate_dports_gnome_zenity/work/zenity-2.18.2/help/"; fi; \

(cd bg/ && \

  `which xml2po` -e -p \

    "${d}bg/bg.po" \

    "${d}C/zenity.xml" > zenity.xml.tmp && \

    cp zenity.xml.tmp zenity.xml && rm -f zenity.xml.tmp)

What gives?
