The underlying problem is illustrated this:

cagney@tomago$ cat /proc/2151/stat
cat: /proc/2151/stat: Permission denied
cagney@tomago$ ls -l !$
ls -l /proc/2151/stat
-r--r--r-- 1 root root 0 Jan  7 17:46 /proc/2151/stat
cagney@tomago$ cp /proc/2151/stat /tmp
cp: cannot open `/proc/2151/stat' for reading: Permission denied
cagney@tomago$ read < /proc/2151/stat x
-bash: /proc/2151/stat: Permission denied

The FRYSK testsuite assumes that it can follow process chains all the way to PID
one.  With SELINUX enabled that may not be possible.

Disabling SELINUX lets the testsuite work.
