Problem to install wlan driver !

[Dellacherie Stephane]

Hello,

I have an internal WLAN PCI cards in my laptop but I do not succed to 
install the drivers by using linux-wlan-ng-0.2.1pre23 or
linux-wlan-ng-0.2.1pre25

When I run "Configure", I obtain the following informations from my laptop :

Build Prism2.x PCMCIA Card Services (_cs) driver? (y/n) [y]: y
Build Prism2 PLX9052 based PCI (_plx) adapter driver? (y/n) [n]: y
Build Prism2.5 native PCI (_pci) driver? (y/n) [n]: y
Build Prism2.5 USB (_usb) driver? (y/n) [n]: y
 
Linux source directory [/lib/modules/2.6.5-1.358/build]: y
Linux source tree y is incomplete or missing!



Does-it mean that the linux-wlan-ng-0.2.1pre23 or
linux-wlan-ng-0.2.1pre25 are not ok for the kernel 2.6.5-1.358 ??? 
Is-there something to update in my kernel to make ok the installation of 
the drivers ???

Thank you for the info..
