[Hans Fredrik Nordhaug]
We are not using the general name "no" (anymore), but the two more specific names "nb" and "nn". (If you really need "no.po" it should be a symlink to "nb.po".)
There are more to this. Want to use 'nb', but until glibc locales have been updated to make nb_NO a real locale instead of an alias to no_NO, it is not possible to get gettext to use the 'nb' translations. So before glibc bug libc/2931 (RedHat bug #83276, Debian bug #206474) is fixed we have to store translations used by gettext using the obsolete 'no' language code. Other programs not using gettext or the glibc locales should be modified to use nb imediately.
