With ipkg there is also small problem as there are two different 
versions of it... And two formats of package.

First it was shell script which handled .ipk "v1 packages" which were 
tar.gz archives. This version was used by Sharp in their Zaurus system 
and on some others systems.

Second version is what we know as ipkg - written in C, handle old style 
packages and "v2" ones which are same as Debian ones ('ar' archives).

opkg-nogpg should be fine

From development point of view it is dead.
