Installing R on RedHat7.0

Thanks!  Building from source worked, and the demos all run.  Several
others report that R runs smoothly on RedHat7.

However, not all the tests in $R_HOME/tests succeed.  When I do "make
test-Examples" in that directory,  it fails executing "base-Ex.R" in the
"eigen" section, with the error:

	Error: abs(sm %*% V - V %*% diag(lam)) < 60 * Meps is not TRUE

This appears to be a numerical precision problem.  Checking, Meps (i.e.
.Machine.double.eps) is 1.084202e-19.  Is this a reasonable value for a
Pentium III?

If I rerun test-Examples, all the remaining tests complete with no problem.

Similarly, make test-Specific fails during arith-true.R, with many tests
returning FALSE.

Have others who run R on RedHat7 run these tests? It seems that either
there's a serious compiler problem, or the .Machine variables are getting
set wrong, or I have a hardware problem.
