Sure. It's below. I waited to double-check that the advice works on a
nice clean 0.37. It does.
I don't mention that I only built the client as the advice should also
apply to anyone trying to build the server as well.

Just FYI: xlc compilers are also now available for MacOS X so assuming
xlc and AIX go hand-in-hand may be erroneous.

US204-005 )
While I wouldn't expect to find its use particularly prevalent, in
high-performance scientific applications such as the Virginia Tech G5
Supercomputing Cluster, it has already reportedly been used.

There's a lot of other experience that perhaps should be documented
somewhere--especially since the list archives searchability appears
sketchy. Search for xlc or aix and you will not find any of my recent
posts to the dev or users lists and the various ensuing conversations
-- I didn't anyway. I also do not see a way to order search results by
date, which will likely be more and more a problem as time progresses
and suggestions about alpha-level Subversion may precede more relevant
discussions about newer versions of Subversion.
