oclHashcat on debian (The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) linux)

[hashfreak028]

Hmm I downloaded catalyst radeon driver for linux and it says, that my card is not supported although I chose the driver with their dumb " Select the type of system that you have; Select the product family your product belongs to; ...". So I followed the instructions I got from the previous reply link.
I don't know why to install linux-headers and for what, but they say so, so:
Somehow I installed linux-headers and search for catalyst in the packages and found some fglrx for ati radeons, so I installed it.
But first of all, I had to include some links in apt-get/sources.list and run apt-get update, but why? Why there weren't all the package links? Tell me please why.
According to wikipedia fglrx is a radeon driver, but still I get this error in oclHashcat:

Code:

./oclHashcat64.bin: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by ./oclHashcat64.bin)
./oclHashcat64.bin: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.15' not found (required by ./oclHashcat64.bin)

Ok so I try to install the catalyst driver I downloaded manually from support.amd.com again and it works. WTF? Isn't fglrx the same?, why it would want to install the driver twice? How come my card is no longer unsupported? So I'm stuck with the installation. I need to choose between some SuSE and RedHat packages. There are:
Package generation heading
SuSE/SLE10-IA32
SuSE/SLE10-AMD64
SuSE/SLE11-IA32
SuSE/SLE11-AMD64
SuSE/SLE10-IA32
SuSE/SUSE121-IA32
SuSE/SUSE121-AMD64
SuSE/SUSE122-IA32
SuSE/SUSE122-AMD64
SuSE/SUSE123-IA32
SuSE/SUSE123-AMD64
SuSE/SUSE131-IA32
SuSE/SUSE131-AMD64
and then
Packages for other distributions
and then
RedHat/RHEL5_64a
RedHat/RHEL6_64a
RedHat/RHEL5
RedHat/RHEL6
What the HEL? I have Debian!
What should I choose? I assume Packages for other distributions. But should I continue? I already have fglrx.
