First, "Global CSE elimination suppressed" just means some optimizations aren't going to be performed, which shouldn't be a big deal.

Now, "Memory exhausted" means you need more virtual memory available to you compiler. You say "with 256 meg of memory", but that is physical memory not virtual memory. The first thing to check is how much swap space your system has and make sure it isn't all being used when you try to build Perl. The next possible problem is artificial resource limits -- using "root" to do the build is one way to avoid all of those.
