Good to know it's reproducible, and not just me  :)

To fix, find the checking library in /lib64/libldap_r-2.4.so.2.

[root@localhost repmgr-2.0]# cd /lib64/
[root@localhost lib64]# ls -l libldap*
lrwxrwxrwx. 1 root root     20 Dec  8 09:23 libldap-2.4.so.2 -> libldap-2.4.so.2.5.6
-rwxr-xr-x. 1 root root 317200 Apr 29  2013 libldap-2.4.so.2.5.6
lrwxrwxrwx. 1 root root     22 Dec  8 09:23 libldap_r-2.4.so.2 -> libldap_r-2.4.so.2.5.6
-rwxr-xr-x. 1 root root 335264 Apr 29  2013 libldap_r-2.4.so.2.5.6

Ok, there are two copies, retain one and unlink other.

[root@localhost lib64]# unlink libldap_r-2.4.so.2
"


I did the above and success:

PATH=/opt/PostgreSQL/9.6/bin:$PATH make USE_PGXS=1 clean all
...
I am going to agree with John's comment upstream that unlinking a file seems to be dubious. You might want to try linking the file back up again after you have installed repmgr and see if it causes any issues.

I'll have a word with our UNIX team about unlinking this (and relinking afterward) tomorrow (they're gone for the night ... :) ) and report back, but it certainly is looking promising again! :)

Here's what I currently see in /lib64 for libldap files ...

$ ls -l /lib64/libldap*

lrwxrwxrwx 1 root root   21 May 11 12:42 /lib64/libldap-2.4.so.2 -> libldap-2.4.so.2.10.3
-rwxr-xr-x 1 root root 337K Feb 23  2016 /lib64/libldap-2.4.so.2.10.3
lrwxrwxrwx 1 root root   23 May 11 12:42 /lib64/libldap_r-2.4.so.2 -> libldap_r-2.4.so.2.10.3
-rwxr-xr-x 1 root root 365K Feb 23  2016 /lib64/libldap_r-2.4.so.2.10.3
lrwxrwxrwx 1 root root   23 May 16 17:06 /lib64/libldap_r.so -> libldap_r-2.4.so.2.10.3
lrwxrwxrwx 1 root root   21 May 16 17:06 /lib64/libldap.so -> libldap-2.4.so.2.10.3

Regards,

Martin.
