This line does not work on my system. 'cat' produces "3.2.46", while /lib/modules contains:

2.6.32-5-amd64	2.6.39-2-amd64	3.1.0-1-amd64  3.2.0-2-amd64  3.2.0-4-amd64
2.6.38-2-amd64	3.0.0-1-amd64	3.2.0-1-amd64  3.2.0-3-amd64

so I guess "depmod `uname -r`" would be the right thing to do, which is the same as "depmod" by itself. With this the "make modules_install" seems to succeed.
