Ok gents and ladies. i went in for round two and still no go. but this time I will list here an exact answer as to what the device has said for the dpkg part.

i entered this:
dpkg -i gcc-3.4_3.4.4cs2005q3.2-5.osso8_armel.deb libc6-dev_2.5.0-1osso10_armel.deb linux-kernel-headers/linux-kernel-headers_2.6.16.osso11-1_armel.deb

The n810 said:
dpkg: error processing gcc-3.4_3.4.4cs2005q3.2-5.osso8_armel.deb (--install):

dpkg: dependency problems prevent configuration of libc6-dev:
libc6-dev depends on linux-kernel-headers; however;
package linux-kernel-headers is not installed.
dpkg: error processing libc6-dev (--install):
dependency problems - leaving unconfigured
errors were encountered while processing:
gcc-3.4_3.4.4cs2005q3.2-5.osso8_armel.deb
linux-kernel-headers/linux-kernel-headers_2.6.16.osso11-1_armel.deb
libc6-dev
/home/user #

my hypothesis is that libc6-dev did install but unconfigured and the other two didn't.

which leaves to wonder why? i put this question to your superlative deductive reasoning to figure this out. and once again as I am always saying. And thats many THANX
