Fresh install of Fedora 29 on bare metal and 'dnf update'. Build VPP:
 $ git clone https://gerrit.fd.io/r/vpp
 $ cd vpp
  $ make install-dep
  $ make pkg-rpm

Install VPP RPMs:
  $ sudo rpm -i build-root/*.rpm
    file /usr/include/rdma from install of vpp-devel-19.08-rc0~196_g7fe470a54.x86_64 conflicts with file from package kernel-headers-5.0.9-200.fc29.x86_64

NOTE:
One thing that I don't understand is that the installed kernel is 5.0.11-200.fc29.x86_64, but the error message is 'conflicts with file from package kernel-headers-5.0.9-200.fc29.x86_64'. There are not any 5.0.9-200 directories on my system.
$ ls /usr/src/kernels/
5.0.11-200.fc29.x86_64 5.0.11-200.fc29.x86_64+debug
$ sudo find / -type d -name "5.0.9-200" -print 2>/dev/null
