Follow-up Comment #4:

Its great that the problem has been fixed. I am marking this issue as closed.
However, discussion is not unlocked, so if you do find the cause of the
problem, it would be great if you could post it as a comment here for the
future (other users that might take the same steps).

If you are interested in learning more about the `.libs' directory and
Libtool, its manual <https://www.gnu.org/software/libtool/manual/> is a good
starting point. In summary, its created to facilitate portability of shared
libraries (installation on a wide variety of operating systems). 

Since the Gnuastro programs depend on a shared library, their main executable
file before installation (for example `bin/cosmiccal/astcosmiccal') is not a
binary file, its actually a shell script (created by Libtool). This shell
script calls the actual compiled (binary) executable, which is in the `.libs'
directory along with some other information to help in portability. But after
installation the binary file is placed in the installation directory and the
`.libs' file is no longer necessary.
