sci-physics/cernlib-2006 does build on sparc. However, it ignores CFLAGS (and FFLAGS) from make.conf, substituting its own defaults. For CFLAGS, it forces -O3 (in general, not a good idea) ignores -mcpu= from make.conf CFLAGS, and even sometimes FORCES -mcpu=v7. This results in building the C portion for essentially an SS2 and quite suboptimal performance on any sparc system anyone is likely to have.
Fortran build is similar, although I did not notice any forced -mcpu=v7 flags.
Since it builds, I'm giving it ~sparc for testing, but it really should use my CFLAGS/FFLAGS, not what it thinks I need unless there is some compelling reason to do otherwise. Please see Bug 59506 for an explanation.
Add CC sparc.
I will take a deeper look how to enforce users CFLAGS/FFLAGS as well as a decent src_test procedure. Useful for other arches anyway.
just commited some cernlib fixes allowing user's flags and a src_test. Give it a try when you can. I will also propagate these changes in other cernlib packages (paw, geant, cernlib-montecarlo).

That fixes the CFLAGS, thanks. Also, it does run many tests now. Apparently, it runs them successfully (at least, src_test does not take the "die" branch, and as far as I could tell from watching it run, everything reported success).
So far as I am concerned, this bug is fixed and you can close it.
Thanks for your help.
