DPDK "ninja install" issue

[Templin (US), Fred L]

Never mind, I found the problem. On Ubuntu 22.04 there was apparently already some
form of installation of meson and ninja, but then I hit it again with "pip3 install". I have
seen many times now that on Ubuntu you need to be very careful not to use pip3 to
install something already installed by apt and vice-versa - the two packages seem to
have the ability to clobber the work done by the other in strange ways, and I am
surprised this doesn't cause widespread problems.

Bottom line - I was able to start from scratch and now have DPDK built and installed.
