That's not at all clear: what is `ia32e'? Depending on what it means R will work in 32- or 64-bit mode. My hesitation is that when we tried RHEL3 without much happiness on an AMD64 box: it had lots of 32-bit components.

Not likely (it has later software than RHEL3). Building from the sources should be straightforward, but watch the compiler versions. Martin Maechler had problems (with I believe RHEL3) and need to update gcc and g77. The problem was with gcc 3.2.x, and 3.3.3 and 3.4.3 are both fine.
