OK, first off I'm a newbie to *nix so please talk to me as you would a 5 year old

. I've got 2 questions for ya, hopefully someone can shead a bit of light.
First I'm using a Knoppix HD install and any program that I try to run ./configre on, ends with this:
Code:
checking for Qt... configure: error: Qt (>= Qt 3.0.3) (headers and libraries) not found.
Please check your installation! For more details about this problem,
look at the end of config.log.
I just download the .gz files to my home dir then extract them into a new folder in my home dir. Should I be extracting these someplace else? This QT error happens reguardless of if I su first or not, and this error happens with all of the .gz files that I've downloaded thus far.
My second question which is unrelated to the first is reguarding synaptic. I have successfully installed one or two things with this, but when ever I try something with dependencies wierd stuff happens. Say for example I try to get Kdetoys. When I hit the proceed button, the pop-up says:
Code:
158 packages were kept back and not upgraded
1 new package installed
1 package upgraded
119 packages removed
180mb will be freed after installation
I actually proceeded once installing some other package and ended up messing up my whole KDE and I had to reinstall everything. I mean if I'm installing new stuff shouldn't I be loosing free disk space and not gaining space? I'm wondering if there's a setting that I've overlooked or some step in the procedure that I'm skipping.
Thanks anyone who can tell me what I'm doing wrong.
