ubuntu trusty dahdi-dkms does not install due to compile errors and missing files

When installing asterisk-dahdi, which in turn install dahdi-dkms I get:

...
Setting up dahdi-dkms (1:2.5.0.1+dfsg-1ubuntu3) ...
Loading new dahdi-2.5.0.1+dfsg-1ubuntu3 DKMS files...
First Installation: checking all kernels...
Building only for 3.13.0-30-generic
Building for architecture x86_64
Building initial module for 3.13.0-30-generic
Error! Bad return status for module build on kernel: 3.13.0-30-generic (x86_64)
Consult /var/lib/dkms/dahdi/2.5.0.1+dfsg-1ubuntu3/build/make.log for more information.
...

This file is attached.

From this point on I tried to solve it manualy.
Searching the intenet I found the attached patch the partialy solved the problem.
I could "make all".
When I tryed "make install" I got:

...
install -m 644 ../XppConfig.pm USB_FW.hex FPGA_FXS.hex FPGA_1141.hex FPGA_1151.hex FPGA_1161.hex PIC_TYPE_1.hex PIC_TYPE_2.hex PIC_TYPE_3.hex PIC_TYPE_4.hex /usr/share/dahdi/
install: cannot stat ‘USB_FW.hex’: No such file or directory
install: cannot stat ‘FPGA_FXS.hex’: No such file or directory

install: cannot stat ‘PIC_TYPE_3.hex’: No such file or directory
install: cannot stat ‘PIC_TYPE_4.hex’: No such file or directory
make[1]: *** [install] Error 1
...

I then downloaded dahdi-linux-complete-2.9.1.1+2.9.1.tar.gz from elsewhere and extracted the missing ".hex" files to the /usr/src/dahdi-2.5.0.1+dfsg-1ubuntu3/drivers/dahdi/xpp/firmwares directory.
The "make install" proceeded normally.

Could you guys take a look at this?

One more thing: at the end of installations it says: "If you have not done so before, install the package dahdi-tools".
but:
# apt-get install dahdi-tools
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package dahdi-tools

What is incorret: the script message or apt-get message?
