This may depend on the way the rpm was made, but
it might have happened that mod_perl-2 was installed
relative to an Apache2/ subdirectory (so as to not
overwrite existing mod_perl-1 files). Does
 perl -MApache2 -Mmod_perl -e 'print $mod_perl::VERSION'
report the upgraded mod_perl-2?

That means that mod_perl wants to install things relative to
an Apache2/ subdirectory. Try configuring as
  perl Makefile.PL MP_INST_APACHE2=1 ....
which will do this for you. See
http://perl.apache.org/docs/2.0/user/install/install.html#Installing_mod_perl_from_Source
for further details.

With the installation into the Apache2/ subdirectory, it's
possible to have both mod_perl-1 and mod_perl-2 installs in
the same perl tree - this may be advantageous if you want to
upgrade while still keeping the mod_perl-1 installation
running.

After installing mod_perl-2, you have to adjust @INC
to see things under the Apache2/ subdirectory - you can
do this by putting a
   use Apache2;
in a startup.pl, or a
   PerlModule Apache2
directive in httpd.conf. See
http://perl.apache.org/docs/2.0/user/config/config.html#Accessing_the_mod_perl_2_0_Modules
for further details.
