(Actually, I think egcs-2.91.66 aka EGCS 1.1.2 *was* released by
someone responsible, it's just buggy...)

Beware that this is not the only one! Several other packages also fail
to load in the same way. When 1.4.0 comes out, builds of R itself will
fail with stock 6.2. (Unless someone can figure out a workaround,
which hardly seems worth the effort. F2c is a workaround, btw, but it
is not standard with RH.)
