Rede Dlink 530t

Olá, recentemente precisei adicionar uma placa de redes dessas num servidor HP com Debian nem tenho a necessidade de tanta velocidade, só pq foi só essa placa q funfa!
iniciei os problemas.
primeiro nao tinha os headers, e eu instalava, mas nao funcionavam, consegui um passo a passo daqui, e pude levar o erro mais adiante
agora que já instalei os headers, dá o seguinte erro:

An error has occurred during the compile proces which prevented
the installation from completing.
Take a look at the log file install.log for more informations.
Installation of sk98lin driver module failed.

e o final do install.log é:

misc/Kconfig
misc/Configure.help

+++ Compile the driver
+++ ====================================
make: Entrando no diretório `/usr/src/linux-source-2.6.18'
Building modules, stage 2.
MODPOST
make: Saindo do diretório `/usr/src/linux-source-2.6.18'
+++ Compiler error

não sei o que pode ser agora, e nem como posso resolver!
