We found that if we provide --enable-tap-tests switch at the time of PG sources configuration, getting this below error
"

look like this is happening because the Perl-IPC-Run package is not available on SLES 12 where Perl-IPC-Run3 is available.
Srinu (my teammate) found that IPC::Run is hard coded in config/check_modules.pl and if we replace Run to Run3 it works (patch is attached, created by Srinu)
Do we have any better option to work without this workaround?
