libtool: link: cannot find the library `/usr/local/apr/lib/libexpat.la'

I got this error, when install apache on gentoo linux, rather emere app-admin/apache-tools ends with error:

libtool: link: cannot find the library `/usr/lib64/libexpat.la' or unhandled argument `/usr/lib64/libexpat.la'

I found such way to solve this issue:

cd /var/tmp/portage/www-servers/apache-2.2.22-r1/work/httpd-2.2.22/srclib/apr-util/xml/expat/
./configure
# make
# cp libexpat.la /usr/lib/

than, I can emerge apache without problem and errors.
