It's definately always ./Configure - helped out a bunch of people getting the card to work. It sounds like for some reason (maybe you untarred the driver in a FAT partition?), the Configure script is not set as executable. Easy to fix.
Code:
chmod a+x Configure
Do that just before you type 'make', after you've 'cd'ed into the directory.
By the way, I believe you can also replace typing 'make' with these two lines:
Code:
./Configure
make driver
