I don't think that this necessarily prevents the possibility of OSX 
support via fink, but it's worth remembering that translation packages 
are not 'by definition "noarch"' - if the packages contain compiled 
gettext .mo files, those files may be machine-specific.  As noted in 
http://www.gnu.org/software/autoconf/manual/gettext/MO-Files.html

In practice, it seems that the GNU gettext utils will support either 
endianness, and generate little-endian .mo files regardless of host 
byte-order (the discussion thread at 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=468209 is informative 
here) so that you can get away with treating .mo files as noarch, but 
you might not want to do so in some cases (notably, for the discussion 
in that bug report, on slow-CPU (e.g. embedded) big-endian devices).

If for some reason you were wanting to support non-GNU libc based 
operating systems (like Solaris, which I realize is pretty irrelevant in 
this context) their gettext() implementation does not support automatic 
conversion of .mo files, and therefore packages containing them would 
not be architecture independent.
