Problem running benchmark

[David Bernier <david250@videotron.ca>]

I'm trying to build from source code PARI/gp. My operating system is
Linux CentOS 6.8 for the x86_64 architecture.

CentOS is a clone of the Red Hat Enterprise Linux distribution.

I have the Linux kernel 2.6.32-642.13.1.el6.x86_64 .

I installed gmp , and I have the readline library.

The symbols not found may be related to the Terminfo (formerly Termcap) 
library.

After ./Configure and "make all", the first error sign is in:
"make bench".

I have been looking for the source of this problem on the Internet, and
haven't come up with a solution.

Below, please find the transcript of the "make bench" command.

Thanks for the help.
