Yes.

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.
