ExternalLibraries pciutils currently does not compile on OSX (#1658), it hard-codes the compiler to be gcc (
#1657), it does not search for a system installed version of itself (those can actually exist on Linux machines, #1669), and mis-behaves in that its VERBOSE setting is the default (ie it outputs all shell commands it executes in configure.sh).
libpciutils was added in ticket
#1621 and was not part of the last release so we are not bound be the decprecation policy.
Since only PAPI makes use of it, and PAPI compiles without, I would suggest to comment out libpciutils for the release thornlist.
This is marked "blocker" due to #1658 preventing any ET build on OSX machines.
