Hmm.

As a last resort, there are alternative commands to a2ping I'm aware of.

If "ps2epsi", "epstool", and "epstopdf" all work on your system,
I can provide a variant of Makefile which don't rely on a2ping.

How to check:

(You might need to install missing commands if any.)

$ ps2epsi SMPdesign/CPUvsEnet.eps /tmp/CPUvsEnet.epsi
$ epstool --copy --bbox --ignore-errors /tmp/CPUvsEnet.epsi /tmp/CPUvsEnet.epsij
$ cat /tmp/CPUvsEnet.epsij | epstopdf --filter --outfile=/tmp/CPUvsEnet.pdf

If /tmp/CPUvsEnet.pdf (Figure 6.12 in perfbook) is generated, those three
commands should be working properly.

I tried these commands this February when Fedora 28 updated Ghostscript to
9.22, and a2ping (2.77p) stopped working.  Luckily, a2ping's maintainer
released 2.83p in March.

        Thanks, Akira
