apt-get problems for unmet dependencies

[roberto <robcatanuto@yahoo.it>]

hello,
i have two main questions:

1) since someone else installed Debian on this pc i am working on, i need to know how to check
which version i am currently using of Debian (stable/testing/unstable). These all infos i got from
uname:

	$uname
	Linux 2.4.21 i686 unknown


2)i try to install the following packages via

	#apt-get install <package-name>

 1) tcl8.3
 2) tcl8.3-dev
 3) tk8.3
 4) tk8.3-dev

no problems with 1,2,3 but when i come up to the last i receive error message like this:

 	Sorry, but the following packages have unmet dependencies:
 	tk8.3-dev: Depends: xlibs-dev but it is not going to be installed
 	E: Sorry, broken packages

 and prompts me again.

I tried also this:
	#apt-get install xlibs-dev

and i got the following:

	Sorry, but the following packages have unmet dependencies:
 	xlibs-dev: Depends: xlibs (= 4.3.0-0ds2.0.0woody2) but 4.1.0-16 is to be installed
 	E: Sorry, broken packages

Any idea regarding this problems?

Thank you in advance!
