Luca,

I don't know if you figured this out or not but in case you didn't I ran into 
the same thing today while working with the 2.6.32 patch set.  The missing 
header (bitsperlong.h) is located in the kernel tree at

   /usr/src/linux/arch/<you arch>/include/asm

where <your arch> is x86 for most of us.  This needs to be available in 

   /usr/include/asm

for the build to work.  This header file was added recently to the kernel tree.  
I suspect this happened with the 2.6.31 cycle but I have not checked to see if 
this is the case.  The newest linux-headers package in Gentoo is 2.6.30 and it 
is missing this file.
