With what error message?

What Ruby gem?

Well it is there:

rpm -qlp postgresql10-devel-10.1-1PGDG.f27.x86_64.rpm | grep libpq-fe.h
warning: postgresql10-devel-10.1-1PGDG.f27.x86_64.rpm: Header V4
DSA/SHA1 Signature, key ID 442df0f8: NOKEY

Previous versions used version numbering also:

https://yum.postgresql.org/9.6/fedora/fedora-26-x86_64/

postgresql96-devel-9.6.6-1PGDG.f26.x86_64.rpm

My guess it that the config script for the gem is not taking into
account that Postgres changed from a three part versioning system X.Y.z
to a two part system X.y(where lower case is minor version) from 9.6.0
to 10.1.
