[CentOS] weird RPM dependency error; '/bin/sh' needed, but is provided

I'm circling back to this topic:

I've asked the LTB folks about the symptoms I report, and they can't find
anything mysterious going on.

They directed me to their SPEC file:

https://github.com/ltb-project/openldap-rpm/blob/master/SPECS/openldap-ltb.spec

Further, I tried a rebuild of their source RPM on my CentOS 7.6.1810
host, and the resulting RPM yielded the same symptoms:

  http://ltb-project.org/archives/openldap-ltb-2.4.47-1.el7.src.rpm

I can directly install the related RPMs on a CentOS 7.6.1810 host;
it seems specific to my effort to building a private RPM database.

I don't see any updates to the 'rpm' package itself that might
address what I'm seeing.
