> Thanks for the hints.  They made the problem easy to find.  The change in r23225 on October 7 is causing the problem.  It made GnuCash set XDG_DATA_DIRS if it is being installed in a non-standard location. Unfortunately it sets it to something that won't work on my machine.

MacPorts installs to /opt/local and its version of xdg_run_command_on_dirs knows to look in /opt/local/share so everything works fine if XDG_DATA_DIRS is not set.  Unfortunately the GnuCash Makefile doesn't know about this and assumes the normal default location of /usr/local/share.

Instead I changed it to use the compile time value of XDG_DATA_DIRS as a default if it is set.  If it is not set, the path will have a double colon in it, but that shouldn't hurt.  I'll check this in if no one sees any reason not to.

If you mean you did

-     echo "XDG_DATA_DIRS=$(prefix)/share:{XDG_DATA_DIRS}:/usr/local/share/:/usr/share/" >> $@.tmp; \
+     echo "XDG_DATA_DIRS=$(prefix)/share:${XDG_DATA_DIRS}:/usr/local/share/:/usr/share/" >> $@.tmp; \ 

then I think that's right and what Geert meant to do in the first place. is munged, then parsed in gnucash-bin.c. I don't think that the separators are passed as-is to the OS.
