opkg from my pc

I set all

/etc/opkg/arch.conf /etc/opkg/noarch-feed.conf
/etc/opkg/base-feed.conf /etc/opkg/opkg.conf
/etc/opkg/beagleboard-feed.conf /etc/opkg/perl-feed.conf
/etc/opkg/debug-feed.conf /etc/opkg/python-feed.conf

files to get ipk packages from my pc.

Yes, it works!
I've installed for example gnash.

But, for example, I can't install vlc, even if it present in the same
directory of gnash.
I have to add same particular instruction in order to add vlc to opkg
