This would seem to be a bug, somewhere...

which jives really badly with the

    if (!is.na(Built <- db["Built"])) {
        Built <- as.list(strsplit(Built, "; ")[[1]])
        names(Built) <- c("R", "Platform", "Date", "OStype")
        Built[["R"]] <- package_version(sub("^R ([0-9.]+)", "\\1",
            Built[["R"]]))
    }

inside tools:::.split_description .  

This is not an architecture-specific bug at all, it just happens to be
tickled by the specific length of "alphapca56-unknown-linux-gnu"!

I'm unsure whether the problem is in read.dcf or whether
split_description could just use strsplit(Built, ";[ \n]") and begone
with it. The latter should be a workaround for you in either case.
