Error while compiling/installing asterisk

Hi,

I try to install a patched (call-completed-elsewhere) version of asterisk 1.4.27-rc1

The compiling works without any errors but when I start the MAKE INSTALL
I get this error:

Can anyone help me?

EDIT:
I have to add something:
On my first make install I got another error:

Is there no one who can help me?
I still have this problem.

P.S. I try to compile/install asterisk on a running elastix-system.

There are only about 10 people who regularly read this forum. Not all of them will understand German. Probably none of them have encountered this error, because they use more common distributions of Linux.

I am rather surprised that ast_free_ptr isn’t declared without having had a problem during the make stage.
