Yeah, it might well be SELinux.  Spectrum should still build on
systems with SELinux enabled, though.  Does Spectrum use extended
attributes?  If not, would it make sense to disable them with -x-1?
In the future, SELinux on the host will require fixing this, but
for now it's better to fix the build error.
