Unable to install pgbouncer-1.25.x on SUSE without errors

Hello Admins,

I am trying to install pgbouncer on SUSE. Downloaded the 1.25.1.tar.gz from
https://www.pgbouncer.org/downloads .

After unzipping the file I ran below commands:
*Configure* — no errors
*Make* - below error :
CCLD pgbouncer
make -C doc pgbouncer.1
make[1]: *** doc: No such file or directory. Stop.
make: *** [/pgbouncer-1.25.0/Makefile:204: doc/pgbouncer.1] Error 2

So I tried making pgbouncer specifically with "make pgbouncer" and no
errors.

Then ran the "make install" and it errored out with the same error even
after only making pgbouncer.

On checking the source tar.gz, it looks like the below files are not
present in pgbouncer-1.25.x version under doc directory.

pgbouncer.1 and pgbouncer.5

Please let me know how to have a clean installation without errors?

Thanks,
Teja.
