[R] R-1.7.1 regression test failure on alphaev68-dec-osf5.1

[Jeff Lewis]

I'm attempting to compile and install R version 1.7.1 for my statistical
geneticists.  It seems to compile correctly -- that is, it compiles
without errors -- but the regression test is failing in the following
manner:

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
> ## log
> stopifnot(all.equal(log(1:10), log(1:10, exp(1))))
> stopifnot(all.equal(log10(30), log(30, 10)))
> stopifnot(all.equal(log2(2^pi), 2^log2(pi)))
> stopifnot(Mod(pi - log(exp(pi*1i)) / 1i) < .Machine$double.eps)
Error: Mod(pi - log(exp(pi * (0+1i)))/(0+1i)) < .Machine$double.eps is
not TRUE
Execution halted
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

I'm compiling on Tru64UNIX 5.1A using DECs C and Fortran compilers and
perl 5.6.0.  I found the above error in a file named
'reg-tests-1.Rout.fail'.  Any help you can give me would be most
appreciated.

Thanks,
Jeff
