more fun with building 9.3beta2

I'm not getting the xml2 and uuid-ossp control files delivered to the
extension directory

I've moved to a CentOS box (and dropped pam):

cat /etc/system-release
CentOS release 6.4 (Final)
uname -a
Linux co-app-jl-d001 2.6.32-358.11.1.el6.x86_64 #1 SMP Wed Jun 12
03:34:52 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

pg_config --configure
'--prefix=/usr/local/pgsql-9.3b2' '--with-ossp-uuid' '--with-libxml'
'--with-libxslt' '--with-openssl' '--with-python'

make world says "PostgreSQL, contrib, and documentation successfully
made. Ready to install."

From "make install" I see only plpython[2]u.control and sql shipped to
/usr/local/pgsql-9.3b2/share/extension (though pgplsql files are there
as well).

template1=# select * from pg_available_extensions()
template1-# ;
name | default_version | comment
------------+-----------------+-------------------------------------------
plpgsql | 1.0 | PL/pgSQL procedural language
plpythonu | 1.0 | PL/PythonU untrusted procedural language
plpython2u | 1.0 | PL/Python2U untrusted procedural language
(3 rows)

Any hints appreciated.
