This is, unfortunately, correct. On the other hand, our personal
experience has been that it is very rare for this to work anyway.
While the idea that Linux is Linux is Linux is a nice dream, the
reality is that each vendor patches up so much of the standard
distribution that Suse Linux is very rarely completely Red Hat Linux
(and often have different bugs, much to our dismay). The LAM team's
advice has always been to compile LAM and your application on the
platform on which you intend to run.

You can't. Other than to know that you should always recompile when
migrating from any platform to any other.

It is something we have talked about. For various reasons, it most
likely will not happen in the 7.0 series of releases. It may happen in
the 7.1 series - We will have to revisit the issue at that time.
