Of course, what I forgot to mention below - and sorry if you know that
already - is that whichever perl modules you pre-load in your main
Apache server config via the startup.pl script, you do not need to "use"
anymore in all your perl scripts or Apache/mod_perl handlers.
(At the cost of having them (insibly) duplicated in all the children
processes).
But it may simplify your migration problems, and you can always tune
this later.

Hi.
About your problem below...
I am not sure that this is going to help, nor even if it is really
relevant to your specific problem. Just trying to give you ideas,
because it reminds me of something.
Below are two configurations, of two of our systems which have slightly
different versions of mod_perl and the rest.
I went through the same kind of problems you're going through, a while
ago when going from Apache 1.x to Apache 2.x, and then again more
recently when there were some changes in the mod_perl naming of modules
between mod_perl 1.9xx and mod_perl 2.0, and then some additional things
happened during a Linux Debian upgrade from Sarge to Etch, which changed
the location where some Apache2 stuff was installed.
And there is still some difference to this day in some Perl scripts or
modules between these two systems, which greatly bothers me, but it
basically works.
The main difference is in the two first "use" statements in our
"startup.pl" script (which I assume you are familiar with, as a way to
pre-load some perl stuff when the server starts).
I do not remember precisely which problems we had, but they were of the
same "general gist" as yours, so maybe this helps.
Here it goes :

If Apache2::compat is loaded, it should create that namespace. Dump
%INC from your script and see if Apache.pm is in it.
