I have been getting the "unable to install gngeo" problem. It's on N800 with OS2007.

My failing install log is like this:
Installing gngeo 0.7maemo-1
(Reading database ... 16777 files and directories currently installed.)
Unpacking gngeo (from .../gngeo_0.7maemo-1_armel.deb) ...
dpkg: error processing /var/cache/apt/archives/gngeo_0.7maemo-1_armel.deb (--unpack):
error setting ownership of `./media/mmc1/roms/neogeo': Operation not permitted
Errors were encountered while processing:
/var/cache/apt/archives/gngeo_0.7maemo-1_armel.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

After I mannually created `./media/mmc1/roms/neogeo', it got installed.
