[Rt-devel] can't locate RT.pm - in 3.8-testing since beta2

[Jason Long]

Something changed in 3.8-TESTING which broke RT on my system. When I 
perform the upgrade and restart Apache, Apache fails to start, with the 
following error in my log file:

 [error] Can't locate RT.pm in @INC (@INC contains:

/etc/httpd) at /opt/rt3/bin/webmux.pl line 82.



I've narrowed down the problem to this 2008-05-15 change.

Here is how I typically do an upgrade:
aclocal && autoconf && ./configure --with-apachectl=/usr/sbin/apachectl 
--with-web-handler=modperl2 && make testdeps

If I add --enable-layout=RT3 to my configure invocation, it seems to fix 
the problem. Is this the right solution? Should I rather do something to 
my Apache configuration so it can find the RT files? Or is it a bug?
Maybe something needs to be mentioned about layouts in the README and/or 
UPGRADING files.
