How do I resolve a build error when installing the atlas-lapack package?

Question

I'm installing the atlas-lapack package on ArchLinux

https://aur.archlinux.org/packages/atlas-lapack

Installation is as follows:

git clone https://aur.archlinux.org/atlas-lapack.git
cd atlas-lapack
makepkg -si

After quite a long installation, I received the following message

ATLAS install complete.  Examine 
ATLAS/bin/<arch>/INSTALL_LOG/SUMMARY.LOG for details.
make[1]: Leaving directory '/home/user/Downloads/atlas/atlas-lapack/src/ATLAS/build'
make clean
make[1]: Entering directory '/home/user/Downloads/atlas/atlas-lapack/src/ATLAS/build'
rm -f *.o x* config?.out *core*
make[1]: Leaving directory '/home/user/Downloads/atlas/atlas-lapack/src/ATLAS/build'
make: *** No rule to make target 'libptf77blas.a', needed by 'libptf77blas.so'.  Stop.
==> ERROR: A failure occurred in build().
    Aborting...

Please tell me how to solve this problem?

Blas package (https://archlinux.org/packages/extra/x86_64/blas/) is already installed on the system.

upd.

Here is the contents of the makefile

include Make.inc

As I understand it, I am missing the libptf77blas.a library?
