No data are displayed which suggests failure to me.

    Odd - since it should fail similarly.

This is the problem.  The 3.3.x compiler versions have given us no end
of trouble.  I see that I should update the install.shtml file to
emphasize the binary a bit more.  What one does there is

    perl install.pl -n

and do not need the tar ball.  Alternatively, the 3.4.3 and 3.4.4
compilers are known to work well.  But the files loaded with a binary
install will run programs faster by 7% (AMDs) to 30+% (P IVs).
