your understanding is wrong.

why not use a module?
why not use a precompiled package?
why not build a package yourself,
if you really need/want to build it yourself?

then, why do you not just apt-get install?

no. it tries to generate a patch against the kernel source tree.
there are many architechtures in that tree, one of which is um.

wget http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.11
grep Kconfig_block ChangeLog-2.6.11
  [PATCH] uml: depend on !USERMODE in drivers/block/Kconfig
   ** and drop arch/um/Kconfig_block **

so this file is no longer there
and our attempt to generate a patch against it fails.

but I think you really just want to use apt-get on the target system, no?
