problems with make install_pccard

[Dinesh S Shenoy]

Hi
I am using a D-link 650 with a laptop running redhat8 
while installing hostap i faced the following problem
after doing "make pccard" when i did "make install_pccard" i got the
following error 
[root at localhost hostap-2002-10-12]# make install_pccard
Module installation directory not valid: '/lib/modules/2.4.18-14  '
Most probable cause for this is modified kernel headers.
You will need to install module file (driver/modules/hostap_*.o) manually.
make: *** [install_check] Error 1
can any1 help
thanxs a bunch
