peter/brian:  thank you for the help.  i can now report that gentoo 
amd64 can compile R just fine, too; it requires the f77 USE flag and a 
gcc compiler rebuild first, though.  I also went to gcc 3.4.1.  my 
segfault troubles earlier were caused by my use of f2c.

suggestion: would it be possible to add a code snippet  that tests 
whether the user is trying to compile with f2c---and if so, bombs the 
installation?  (if "f77 --version == f2c" then die)  I know the 
problems are not R's fault, but it can percolate into R and it can 
protect people like myself.



PS: I am still looking for an R wizard who would be interested in 
coauthoring an "R cookbook" ala the "perl cookbook" with me...

As I read the posting guide this is not a help request and not of 
interest, so diverted to R-devel.

Several people including me have built R on AMD64 with 3.3.3.  That's 
compiler of Fedora Core 2, and of whatever version of SuSE (perhaps 
we have on our 110-processor cluster.  I am currently use 3.4.1.

Your error is in Fortran, and we have seen Fortran errors in earlier
versions of the gcc collection so it's the g77 version that is relevant.
