thanks

Hi,
Please, can you estimate whether it can be solved on fakeroot side ?

Now I know, it can.

The problem is that chmod() syscall family does not return EPERM, but 
EFTYPE in this case on *BSD kernels. The linux does not have errno code 
EFTYPE at all.

Please, could you use attached patch.
It is no-op on Linux, as there is no EFTYPE defined, so it is really safe 
change.

When applied, emacs22 builds fine for us.

Many thanks

Petr
